Single sex education FAQ

Single-sex education (teaching boys and girls in separate classrooms or schools) is an old approach regaining momentum. While single-sex education has long existed in many private schools, it’s a relatively new option for public schools. Only 34 single-sex schools were operating in 2004, but by 2017 U.S. Department of Education data estimated more than 1,000 single-gender public schools. Forty-five percent are all boys, 55 percent are all girls, and 83 percent are overwhelmingly Black and Latino.

Since 2006, federal law has supported the option of single-sex education. when Education Secretary Margaret Spellings eased federal regulations , allowing schools to offer single-sex classrooms and schools, as long as such options are completely voluntary. This move has given parents and school districts greater flexibility, but the research on its value remains a matter of debate.

Nature vs. nurture

Before weighing the pros and cons of single-sex education, consider the influences of “nature versus nurture.” Many factors affect each child’s learning profile and preferences:

  • Some factors relate to the child’s nature, such as gender, temperament, abilities (and disabilities), and intelligence.
  • Other influences stem from the way parents and society nurture the child: Family upbringing, socioeconomic status, culture, and stereotypes all fall under the “nurture” category.

Advocates of single-sex education argue for the value of separating children from a number of different angles. The most prominent advocate is psychologist and physician Leonard Sax, whose books Why Gender Matters (2005), Boys Adrift (2007), and Girls on the Edge (2010), argue that boys and girls are inherently different and need different educational experiences. Others have argued that the success of women’s colleges point to a value in female-only education, where the chroniclers of the boys growing academic struggles compared to their female peers suggest that boys need girl-free education to fight the stereotype that boys can’t read.

Critics point to a lack of evidence for such claims, summarized by a 2008 New York Times article, which explained that “many academics and progressives tend to find Sax’s views stereotyped and infuriating.” They point out that studies on the impact of single-sex education on learning often do not account for the fact that most single-sex schools are selective or draw from a different population than coeducational public schools. Former president of the American Psychological Association, Diane F. Halpern co-published “ The Pseudoscience of Single-Sex Schooling” with other scholars, lambasting sex-segregated education as “deeply misguided, and often justified by weak, cherrypicked, or misconstrued scientific claims.” The subject even inspired a New York Times debate where researchers and pundits squared off about the benefits and bluster of single-sex learning.

So, who’s right? Below are arguments both for and against single-sex education.

Making the case for single-sex education

Those who advocate for single-sex education in public schools argue that:

  • Some parents don’t want their children to be in mixed-gender classrooms because, especially at certain ages, students of the opposite sex can be a distraction.
  • A 2019 study from the University of Southern California indicates girls learn better when the classroom temperature is warm, while boys perform better in cooler classrooms. If that’s true, then the temperature in a single-sex classroom could be set to optimize the learning of either male or female students.
  • Evidence suggests single-sex education can broaden the educational prospects for both girls and boys. A 2017 study examining students in Seoul, Korea, concluded, “male high school seniors attending all-boys schools show higher levels of science interests…than their counterparts attending coeducational schools.”
  • A 2015 study out of Switzerland also reports, “[F]emale students in all-female classes experience less stereotype threat and perform better in their mathematics grades than their female peers in coeducational classes.”
  • Advocates claim co-ed schools reinforce gender stereotypes, while single-sex schools can break down gender stereotypes. Girls are free of the pressure to compete with boys in male-dominated subjects such as math and science, while boys can more easily pursue traditionally “feminine” interests such as music and poetry.
  • Some research offers evidence in favor of co-ed education for boys but single-sex for girls. A 2011 study by Victor Lavy and Analia Schlosser titled “ Mechanisms and Impacts of Gender Peer Effects at School ” determined “an increase in the proportion of girls impose boys and girls’ cognitive outcomes” in elementary schools, caused by “lower levels of classroom disruption and violence, improved inter-student and student-teacher relations, and lessened teacher fatigue.”

What critics say about single-sex education

Those who claim single-sex education is ineffective and/or undesirable make the following claims:

  • The impact on learning isn’t conclusive. For instance, in one of the few studies that controlled for a host of parental, individual and school level factors, researchers analyzing Irish schools (where about one third of the students attend gender segregated schools) found no “significant difference in performance for girls or boys who attend single-sex schools compared to their mixed-school peers in science, mathematics or reading.”
  • Few educators are formally trained to use gender-specific teaching techniques. However, it’s no secret that experienced teachers usually understand gender differences and are adept at accommodating a variety of learning styles within their mixed-gender classrooms.
  • Gender differences in learning aren’t the same across the board; they vary along a continuum of what is considered normal. For a sensitive boy or an assertive girl, the teaching style promoted by advocates of single-sex education could be ineffective (at best) or detrimental (at worst).
  • It doesn’t teach genders to work together. Students in single-sex classrooms will one day live and work side-by-side with members of the opposite sex. Educating students in single-sex schools limits their opportunity to work cooperatively and co-exist successfully with members of the opposite sex.
  • It perpetuates gender stereotyping. For instance, the ACLU opposes single-sex schools, claiming they are based on “junk science” to perpetuate “disturbing gender stereotypes” and are a “waste of time” that divert attention from more valuable reforms, such as reducing class size and increasing teacher training. Or as Diane F. Halpern’s put it in “The Pseudoscience of Single-Sex Schooling” “…sex segregation increases gender stereotyping and legitimizes institutional sexism.”

Measuring public perception

How does the public view single-sex education? The “average” adult has a different opinion than the graduates of these schools.

In a 2022 poll by YouGov only 25% of adult men surveyed thought all-boys schools were “better” than co-ed schools, with the same percentage viewing them as “worse.” Adult women were less enthusiastic – only 17% thought all-boy schools were superior, with 21% regarding them as worse. Public opinion of all-girls schools was a bit more generous: 25% of men thought they were better for girls than coed schools, and 22% said they were worse, while 20% of women viewed all-girls schools as better than coeds, with 19% claiming they were worse.

People who actually attended single-sex schools were far more supportive. Men who attended all-boys schools were 45 percent positive, claiming it was better than coed, with 29 percent saying they were worse. Women who attended all-girls schools were 41 percent positive, and 26 percent negative.

Many (often most) people answered the survey question with “not sure” or “no difference.” Their uncertainty mirrors the overall ambiguity of the co-ed vs. single-sex school question. As is true of many educational questions, the answer for any given family often depends on context. For instance, is the school operating in a culture where a single-sex education might offer students a respite from gender discrimination? Is the school (coeducational or single-sex) reinforcing gender stereotypes or working against them? Why might the family want single-sex education for their child? Is it intended to empower the child to succeed and learn or keep them narrowly focused on acceptable gender roles?

Once considered a vestige of the Victorian era, single-sex education is enjoying a resurgence.

BY MARYBETH HUNTER

Members of the FS Community Comment

“My experience … was liberating. I could shed all of the concerns that derive from dual sex environments while in the classroom, but assume my interest in a diverse social life when I chose to. It was all on my terms and that was a powerful dynamic for me.”

—FSO, single-sex college graduate

“[Single-sex college] shaped who I am and better prepared me for the ’real world.’ It made me strong and independent, and gave me confidence in my intelligence and abilities.”

—FS student, single-sex college graduate

“It brought a different type of focus in the classroom, as well as fostering an environment that encourages girls to be more vocal and participate in class.”

—FS student, single-sex high school graduate

Foreign Service parents strive to make the best educational choices for their children, whether in the United States or posted abroad. One option gaining attention is single-sex education, whether at post schools or at boarding schools, in the United States or abroad, in single classrooms or entire schools, from kindergarten through college.

Once considered a vestige of the Victorian era, single-sex education is currently gaining popularity. While the notion may call to mind images of stuffy institutions in idyllic settings, parents and students increasingly value such an education based on the knowledge that differences exist in the ways both boys and girls learn, and that teachers at single-sex schools tailor their teaching style and material to respond to those differences.

The benefits of single-sex education reveal themselves in a variety of ways. For instance, educators at single-sex schools have reported that students attending their schools demonstrate increased confidence in their abilities. Also, proponents of single-sex education argue that such confidence has impact beyond the academic arena by furthering social skills and strengthening future boy-girl relationships.

The common social pressures existing in coed environments are absent, enabling student development without potential distractions from the opposite sex.

Gender-Based Learning Support

Teachers have long been aware that learning styles among students can vary significantly. Research suggests that boys and girls might benefit more from divergent teaching styles that cater to their respective biological profiles.

Take listening skills, for instance: Boys often need to hear instructions at a higher volume of speech for increased comprehension. Likewise, research suggests that boys are more receptive to action-oriented, tactile presentations in the classroom. Another study indicates that, in general, boys are more vocal than girls on teams and prefer group work to independent study.

As for females, researchers find that girls learn better when the nuances of color, texture and smell are introduced. Girls reportedly perform better academically in a warmer classroom, while boys perform better in a classroom at least five degrees cooler than their female counterparts prefer.

In a single-sex setting, instructors can vary teaching methods to bring out the best in their students. When educators tailor their approach to boost academic success, this contributes to psychological and emotional success. That said, it is important to keep in mind that teachers may not always be trained properly to employ gender-specific teaching techniques effectively.

Boosting Self Esteem

Student self-esteem is a concern for parents and educators. Students in a single-sex environment are more likely to be open to various fields of study, and are less likely to be self-conscious or hesitant about trying out new areas of learning atypical for that gender. Structuring the classroom experience around this model allows the student to enjoy the learning experience more deeply.

In turn, students develop greater self-confidence, tackle more challenging or “out of the norm” courses of study, and engage more freely with peers and adults in classroom discussions. Finally, studies show that single-sex education encourages students to develop their own interests and take advantage of leadership opportunities regardless of their gender.

According to New York Times writer Elizabeth Weil, administrators at single-sex schools report “fewer discipline issues, more parental support and higher test scores in reading, writing, and math” than their coed counterparts.

Single-sex schools also reduce social and peer pressure, which has been intensified in recent years by social media. In some cases, removing the presence of girls allows boys to knuckle down and work on their own. Conversely, removing the presence of boys can help girls become more vocal when engaging with peers because they no longer feel intimidated and are less self-conscious.

  • National Coalition of Girls’ Schools (NCGS) – www.ncgs.org

Eliminating gender stereotypes in the classroom has demonstrable advantages, especially in closing achievement gaps. According to Sara Sykes, the director of admissions at Westover School (an all-girl’s school in Middlebury, Connecticut), students at single-sex schools are “more likely to pursue a wider range of fields of study especially in science, technology, engineering and mathematics.”

Ms. Sykes points to a recent National Coalition of Girls’ Schools study, which reported: “When rating their computer skills, 36 percent of graduates of independent girls’ schools consider themselves strong students compared to 26 percent of their coed peers. In addition, 48 percent of girls’ school alumnae rate themselves great at math versus 37 percent for girls in coed schools. In fact, three times as many alumnae of girls’ schools plan to become engineers.”

Likewise, a 2003 study in Psychology of Men and Masculinity indicated that boys from single-sex schools were more than twice as likely to pursue interests in subjects such as art, music, drama and foreign languages compared with boys at coed schools.

However, some researchers caution that single-sex education is detrimental to the academic, social and behavioral development of a child because it can lead to even greater gender discrimination and difficulty relating to the opposite sex as adults.

Developing Diversity

Educational experts argue that diversity is an important consideration in building a quality educational experience. While one might think that homogeneity is fostered in single-sex schools, diversity is often woven into such environments via hiring choices and extracurricular opportunities.

At the all-boys’ Salisbury School in Salisbury, Connecticut, Director of Admissions Peter Gilbert reports that students are constantly exposed to perspectives other than their own through coed opportunities in leadership and community service, as well as daily interactions with opposite-sex school staff members.

Conversely, at girls’ schools, male staff members are often role models, allowing for a relatively mature dialog to occur with the opposite gender and facilitating a mentoring relationship.

The crucial point is that faculty, staff and families at single-sex schools realize that they are all educating students to succeed in an increasingly diverse and complex world. The overall setting may be single-sex, but the perspective is decidedly not one-dimensional.

Single-Sex Education at Post

Some Foreign Service parents have already chosen the single-sex education path for their children. Department of State employee Katherine Lawson and her husband Nestor Sainz weighed all of their options carefully before choosing the all-girl San Silvestre School for their daughter Isabella when their family was posted in Lima, Peru.

“For me, one of the most important aspects of the all-girl learning environment was that by holding the students to high expectations in all areas—math, science, computers, art, poetry, language and physical education—the school broke down gender stereotypes,” says Katherine

“The school seemed to get Isabella’s needs right away and worked with her directly to chart her course of becoming an independent lifelong learner. The seeds of independence and confidence sown in those early years are already starting to take root and flourish now that she is a teenager.”

Know Your Student

Despite the many benefits of single-sex education, educators and researchers agree that not every student will thrive in a single-sex environment. Every student is different. Parents are encouraged to evaluate the talents and needs of their own children to determine if the single-sex setting suits those needs.

Foreign Service families looking to discuss the variety of educational options available should contact the Family Liaison Office Education and Youth team at [email protected] .

Student Opinion

Is Single-Sex Education Still Useful?

advantages of single sex education essay

By Patrick Phelan

  • Jan. 5, 2017

Note: This Student Opinion question was written by a member of an experimental Student Council we ran during the 2015-16 school year. He is a junior at an all-boys’ high school in Boston.

Are all-boys or all-girls schools still useful? What are their benefits? With the emergence of new ideas about the fluidity of gender identity , do they even still make sense?

For example, what happens if a transgender student applies to a single-sex school, or if an enrolled student transitions?

In “ Old Tactic Gets New Use: Public Schools Separate Girls and Boys ,” Motoko Rich provides some context about the educational role of these schools:

Single-sex education, common in the United States until the 19th century, when it fell into deep disfavor except in private or parochial schools, is on the rise again in public schools as educators seek ways to improve academic performance, especially among the poor. Here at Charles Drew Elementary School outside Fort Lauderdale, about a quarter of the classes are segregated by sex on the theory that differences between boys and girls can affect how they learn and behave. ... The theory is generally held in low regard by social scientists. But Ms. Flowers notes that after the school, where nearly all students are eligible for free or reduced-price lunches, started offering the classes two years ago, its state rating went from a D to a C. Similar improvements have been repeated in a number of other places, causing single-sex classes to spread to other public school districts, including in Chicago, New York and Philadelphia.

But questions about the mission of single-sex education have become especially relevant at women’s colleges in recent years thanks to an evolving understanding of gender identity. In a 2014 Op-Ed, “ Who Are Women’s Colleges For? ”, Kiera Feldman writes:

But today, women’s colleges are at a crossroads their founders could never have foreseen, struggling to reconcile their mission with a growing societal shift on how gender itself is defined. A handful of applications from transgender women have rattled school administrators over the past year, giving rise to anxious meetings and campus demonstrations. On April 29, the Department of Education issued new guidance: Transgender students are protected from discrimination under Title IX.

And in another 2014 piece, “ When Women Become Men at Wellesley ,” Ruth Padawer introduces us to Timothy Boatwright, who was raised a girl and checked “female” when he applied, but introduced himself at college as “masculine-of-center genderqueer.” He asked everyone at Wellesley to use male pronouns and the name Timothy, which he’d chosen for himself. Ms. Padawer writes:

Some two dozen other matriculating students at Wellesley don’t identify as women. Of those, a half-dozen or so were trans men, people born female who identified as men, some of whom had begun taking testosterone to change their bodies. The rest said they were transgender or genderqueer, rejecting the idea of gender entirely or identifying somewhere between female and male; many, like Timothy, called themselves transmasculine. Though his gender identity differed from that of most of his classmates, he generally felt comfortable at his new school.

The Resurgence of Single-Sex Education

The benefits and limitations of schools that segregate based on gender

advantages of single sex education essay

Defenders of same-sex schools hold fast to the belief that girls and boys benefit from separate academic instruction. Proponents often point to school experiences documented in landmark reports like The American Association of University Women’s “ How Schools Shortchange Girls ” as evidence of widespread inequities faced by girls in mixed classrooms. Same-sex educational settings are also offered as a way to improve lagging achievement for low-income students of color— mainly boys —in urban public schools. Conversely, opponents claim single-sex education perpetuates traditional gender roles and “ legitimizes institutional sexism ,” while neuroscientists refute the merits of gender differences between girl and boy brains. And rather than creating more equitable schools for nonwhite students, some critics compare separating boys and girls to racially segregated schooling. The disputes pitting ardent supporters against fervent detractors have done little to dampen popularity, however. The prevalence of single-sex public schools has risen and fallen over the years, yet the last decade has seen a major revival. According to the National Association for Single Sex Public Education, only 34 single-sex public schools were in operation in 2004 . That number jumped 25-fold in 10 years: The New York Times reported in 2014 that 850 schools nationwide had single-sex programs. With participation apparently on the upswing, the Department of Education’s civil-rights division offered guidelines on single-sex classes to K-12 public schools last year. Against this backdrop of renewed interest in single-sex schools and classes, the author Juliet A. Williams, a professor of gender studies and associate dean of the Division of Social Sciences at UCLA, takes a deep dive into the social aspects and framing of this hotly debated issue in a new book, The Separation Solution? Single-Sex Education and the New Politics of Gender Equality . She recently shared some thoughts with me on the subject. The interview that follows has been edited and condensed for clarity.

Melinda D. Anderson: A major thread running through the book is that so many people—educators, parents, activists, and politicians—strongly believe in the potential of single-sex education to unleash academic excellence, while the evidence supporting this claim is sparse and insufficient. What would you say is the primary driving force behind its well-entrenched support?

Juliet A. Williams: Some people believe in single-sex education because they had a great personal experience. To other people, single-sex education seems like plain old common sense: They see differences between boys and girls, and they like the idea of creating schools that reflect these differences. Still others look at the failure of U.S. public-school systems and think, “we’ve got to do something; let’s give it a try.” Since the 1990s, there has been a resurgence of interest in single-sex education in public schools serving students in grades K-12. My book takes a look at the arguments driving interest in single-sex public education, as well as the results. What I have found is that single-sex public-school initiatives have been created with the best of intentions, but that they are not delivering the results. At the same time, they are producing some unintended consequences in terms of reinforcing damaging gender stereotypes.

Anderson: Your freshman year at the Philadelphia High School for Girls, an all-girls public magnet for academically gifted students, is compared to “serving time in prison,” a characterization I found peculiar as a graduate of Girls’ High. With the exception of your brief stint in an all-girls school, The Separation Solution? lacks input from current students or alumni of K-12 single-sex schools. Could their perspectives have expanded your analysis of single-sex education? Williams: I’m pretty sure I would have experienced some measure of adolescent angst no matter where I went to school, and looking back, I think it would be a real mistake to conclude that it was because I happened to attend an all-girls [high school] as opposed to a coed one. By the same token, I suspect that many people who flourished in single-sex environments would have had an equally rewarding experience at a coed school. That’s the problem with relying on personal experience to assess what works in education, and what doesn’t. Think of it this way: If I were to write a book about new treatments for cancer, [I wouldn’t] go out and ask people whether they enjoyed their treatment. I would want to know about results. Our kids deserve to grow up in a society that takes their education every bit as seriously as we take our commitment to good medicine.   Anderson: The creation of single-sex academies in the 1950s throughout the South by anti-integrationists aiming to thwart Brown v. Board of Education and keep black boys from being in classrooms with white girls is an interesting tidbit. Today, K-12 single-sex programs are still mostly concentrated in southern states. Can you talk more about this historical footnote?

Williams: Mention single-sex education to most people today, and you are likely to conjure images of elite institutions in bucolic settings, where emphasis is placed not only on rigorously training young minds, but also on building character and developing self-confidence. As I discovered, however, behind the image of single-sex education’s rosy past lies the story of its disturbingly checkered history. After the Civil War, several of the nation’s increasingly diverse, urban school districts moved to create single-sex public high schools to appease xenophobic parents worried about the prospect of students from different ethnic, religious, and class backgrounds rubbing shoulders throughout the school day. In the years following the landmark Supreme Court ruling, the prejudice driving the retreat from coeducational public schools was even more flagrant … amidst racist panic about the inevitability of young white women and young black men forming social bonds across racial lines.

This history is important [yet] I don’t think there are any easy analogies to be drawn between racially segregated schools in the past, and single-sex schools in the present. Many single-sex programs have been initiated specifically to address the unmet needs of underserved students, particularly black and Latino young men, and there is no question that some of the very best single-sex public schools today are ones created to serve low-income students of color. What is a question [though] is whether these schools are great because they are single-sex. So far, there isn’t evidence to show that they are. Instead, the research shows that successful schools, whether single-sex or coed, tend to have certain things in common, like creating strong mentoring relationships and keeping class sizes to a manageable level. When this happens, students benefit—whether or not boys and girls [are separated].

Anderson: The claim that boys and girls are “hard wired” differently, namely the neuroscience of sex-based learning differences, has been refuted by scientific researchers. Still, a belief in its efficacy persists as an education-policy approach and in teacher professional development. How can this be more effectively countered? Williams: While researching this book I learned about a fascinating phenomenon called “the selective allure of neuroscientific information.” In a series of ingenious experiments, a team of Yale researchers found that even the citation of irrelevant neuroscience information can make certain claims seem more credible than they otherwise would be. What this means in practice is that we can be all too easily drawn into accepting even the most poorly substantiated claims about the differences between men and women, provided those claims come dressed up in the commanding rhetoric of “hard-wiring.” What I found is that many of today’s “gender-sensitive” pedagogies are sold to teachers and parents in a deceptively appealing pseudo-scientific jargon of sex difference. That’s not to say that there aren’t real differences between girls and boys. But it is to say that we should be very skeptical of anyone who claims that we can extrapolate from what currently is known. Despite the fact that much of the popular science of sex difference has been debunked, the past decade has seen a proliferation of public-school programs modeled on bogus teachings.

Anderson: The prospect of transgender students recalibrating the single-sex education debate is presented in the book, with the mission and practice of single-sex schooling upended “in new and important directions.” What do you see as the future of single-sex education as growing numbers of students no longer identify with a gender binary?

Williams: It will be interesting to see how single-sex schools address the issue of gender diversity moving forward. The Department of Education’s Office of Civil Rights has been clear that transgender and gender nonconforming students are entitled to protection from sex-based discrimination under Title IX. [All public and private elementary and secondary schools, school districts, colleges, and universities receiving any federal financial assistance must comply with Title IX] Further, all students are entitled to participate in school programs based on their gender identity. One place single-sex public schools may wish to look for guidance moving forward is to the nation’s private women’s colleges. In recent years, several of the most prestigious historically all-women’s colleges have revised their admissions statements to explicitly welcome applications from transgender and gender nonconforming students. In doing so, these colleges are taking important steps to ensure that their commitment to single-sex education doesn’t inadvertently perpetuate bias and intolerance. Anderson: A provision in No Child Left Behind in 2001 helped accelerate the growth of single-sex education—you describe a “surge of single-sex experiments” in public-school classrooms across the country. A co-sponsor of the provision allowing school districts to use grants for same-sex schools and classrooms was former New York Senator Hillary Clinton, who cast single-sex education as furthering public-school choice. Now a candidate for U.S. president, how do you think same-sex education might fare in a Hillary Clinton administration?

Williams: Many officials, including then Senator Hillary Clinton, saw single-sex public education as a promising reform strategy. At the time, federal money was set aside to encourage “experimentation” with single-sex approaches. Since then, hundreds of single-sex public-schooling initiatives have been launched. What have we learned? Predictably, fans of single-sex education loudly proclaim these experiments to be a success —and they have a few carefully chosen examples to prove it. But the real story lies in the overwhelming number of single-sex initiatives that have failed to produce positive results. In 2014, an exhaustive review found no significant proven advantages of single-sex schooling over coeducation, either for boys or for girls. With so many proven approaches to education reform out there, let’s invest in those. Our kids’ lives are too precious to experiment with.

The number of single-sex schools in the United States has climbed steadily in recent years, despite a lack of consensus that such schools lead to academic or psychological outcomes superior to those of coeducational schools. In this introduction to the first part of a special issue on the topic, we review the history of single-sex education in the U.S. and factors that have led to its recent rise. We then review ideological and methodological controversies in the field. Finally, we summarize the eight empirical studies that appear in the issue, highlighting the contributions of each paper to a body of work that we hope will inform educational practice and policy.

Single-sex education refers most generally to education at the elementary, secondary, or postsecondary level in which males or females attend school exclusively with members of their own sex. This report deals primarily with single-sex education at the elementary and secondary levels. Research in the United States on the question of whether public single-sex education might be beneficial to males, females or a subset of either group (particularly disadvantaged youths) has been limited. However, because there has been a resurgence of single-sex schools in the public sector, it was deemed appropriate to conduct a systematic review of single-sex education research.

A number of theoretical advantages to both coeducational (CE) and single-sex (SS) schools have been advanced by their advocates, a subset of whom have focused specifically on the potential benefits of SS schooling for disadvantaged males who have poor success rates in the educational system. The interpretation of results of previous studies in the private sector or the public sectors of other countries has been hotly debated, resulting in varying policy recommendations based on the same evidence. However, no reviews on this topic have been conducted using a systematic approach similar to that of the Campbell Collaboration (CC) or the What Works Clearinghouse (WWC). Thus, the objective of this review is to document the outcome evidence for or against the efficacy of single-sex education as an alternative form of school organization using an unbiased, transparent, and objective selection process adapted from the standards of the CC and WWC to review quantitative studies.

Concurrently with this review of the quantitative literature, we conducted a review of the qualitative literature on the subject of single-sex schooling using parallel coding techniques. Unlike quantitative studies, qualitative studies are not viewed by WWC as appropriate methodology when determining causal relationships. Rather, they contribute to theory building and provide direction for hypothesis testing. Few qualitative studies satisfied the criteria for inclusion. Therefore, the primary focus of this paper is the systematic review of quantitative research.

The following are the major research questions addressed by the systematic quantitative review:

  • Are single-sex schools more or less effective than coeducational schools in terms of concurrent, quantifiable academic accomplishments?
  • Are single-sex schools more or less effective than coeducational schools in terms of long-term, quantifiable academic accomplishment?
  • Are single-sex schools more or less effective than coeducational schools in terms of concurrent, quantifiable indicators of individual student adaptation and socioemotional development?
  • Are single-sex schools more or less effective than coeducational schools in terms of long-term, quantifiable indicators of individual student adaptation and socioemotional development?
  • Are single-sex schools more or less effective than coeducational schools in terms of addressing issues of procedural (e.g., classroom treatment) and outcome measures of gender inequity?
  • Are single-sex schools more or less effective than coeducational schools in terms of perceptual measures of the school climate or culture that may have an impact on performance?

As in previous reviews, the results are equivocal. There is some support for the premise that single-sex schooling can be helpful, especially for certain outcomes related to academic achievement and more positive academic aspirations. For many outcomes, there is no evidence of either benefit or harm. There is limited support for the view that single-sex schooling may be harmful or that coeducational schooling is more beneficial for students.

The Systematic Review Process

The systematic review of the literature consisted of the following steps:

An exhaustive search of electronic databases for citations, supplemented by other sources. This search strategy yielded 2,221 studies.

An initial Phase I exclusion of sources whose subject matter falls outside the defined scope of the study. Criteria used for exclusion in Phase I included:

Population -To be included, the students had to be enrolled in a full-time school. They had to be in elementary, middle, or high school as opposed to college and beyond. Finally, the schools being studied had to be in English-speaking or Westernized countries somewhat comparable to American public-sector schools.

Intervention -The single-sex school had to be one in which students were either completely segregated by sex or were completely segregated for all classes, even if co-located in the same building (i.e., dual academies). Studies of single-sex classes in a coeducational school were excluded from review. This initial screening yielded 379 publications that fit the initial inclusion criteria.

A Phase II exclusion based on obvious methodological considerations (e.g., nonstudy, weak study). On the basis of titles and abstracts, citations that appeared to be essays, reviews, opinion pieces, and similar items were excluded, and only qualitative and quantitative studies that were likely to be codable in Phase III were retained. During Phase II, 114 citations were culled from the 379 items and coded as appropriate for review as quantitative (88) or qualitative (26) studies. Of the 26 qualitative studies, 4 met the criteria for final inclusion and were reviewed separately.

A Phase III evaluation and coding of the remaining quantitative articles. According to the guidelines of the WWC, all studies other than randomized controlled trials, quasi-experimental designs (QED) with matching, or regression discontinuity designs would be excluded prior to Phase III. Under the WWC criteria for inclusion, virtually all single-sex studies would have been eliminated from the review process because of the lack of experimental research on this topic. Therefore, for this review, a conscious decision was made to relax these standards and include all correlational studies that employed statistical controls. By relaxing the WWC standards, the number of candidate studies to be screened in Phase III was greatly increased. A more streamlined and efficient checklist was developed requiring dichotomous responses rather than descriptive responses in order to facilitate rater decision making. To be included in the quantitative review, a study had to use appropriate measurement and statistical principles. A primary criticism of previous single-sex literature has been the confounding of single-sex effects with the effects of religious values, financial privilege, selective admissions, or other advantages associated with the single-sex school being studied. Therefore, in particular a study had to include statistical controls to account for individual differences (e.g., socioeconomic status [SES], individual ability, and age) as well as school and class differences that might account for the differences between single-sex and coeducational schools. Even so, many studies that included at least one covariate lacked other important covariates such as ethnic or racial minority status, socioeconomic status, and grade level or age. Also, it is important to note that the inclusion of covariates cannot control for important unobservable differences between the groups, such as motivation. Because correlational studies cannot adequately address the issue of differences in unobservables (or selection bias), the studies in this review may over or understate the true effects of SS schooling.

The Quantitative Review

Two reviewers coded each study independently, using a quantitative coding guide. A quantitative study was coded for its treatment of the following broad issues: sample characteristics, psychometric properties, internal validity, effect, and bias. Each of these categories had several criteria by which they were coded. To be retained, a study did not have to meet all criteria.

Of the 88 quantitative studies, 48 were eliminated after further review using the coding guide, and 40 studies met the inclusion criteria and were retained. The reasons for the exclusion of these articles were 1) failure to operationalize the intervention properly; 2) failure to apply statistical controls during the analyses; 3) work that was actually qualitative in nature rather than quantitative; 4) work performed in a non-Westernized country and therefore not comparable; 5) work written in a foreign language and therefore not codable by the researchers; 6) failure to draw comparisons between SS and CE schools; and 7) participants not of high school, middle, or elementary school age. In all, 40 studies met the inclusion criteria and were retained in the quantitative review. The following table shows results of each study according to the seven broad questions listed above and is broken into specific criteria within each larger category. Because some studies addressed multiple criteria, the total number of findings is greater than 40. Specifically, there are 112 findings considered in the 40 quantitative studies.

A table summarizing the findings is below . In each row, one of the 32 outcome categories is listed, as well as the total number of studies related to that outcome category and the raw number and percent of findings that either support SS schooling, support CE schooling, are null, or mixed (supporting both CE and SS schooling). While eight of the outcome categories have four or more studies, others have as few as one or two studies. For any outcome category, the percentage of studies falling in any of the dispositions (supporting SS, supporting CE, null, or mixed) and the confidence with which one can use the findings will increase with the number of studies. Therefore, the percentages in the summary table should be treated with caution when only one or two studies appear for that outcome category.

As shown in the Summary Table, every study falls into one of four categories: Pro-SS, Pro-CE, Null, or Mixed. If a study's findings all supported SS schooling for a given outcome variable, it was coded as "Pro-SS". If the study's findings all supported CE for a given outcome variable, it would be coded "Pro-CE". A study was coded "Null" if for all findings regarding that outcome variable, there were no differences between the SS and CE schools. A study was coded "Mixed" if the study had significant findings in opposite directions for different subgroups on the same variable. For example, a study would be coded "Mixed" if on a specific outcome, support was found for single-sex schooling in the case of boys and support was found for coeducation in the case of girls. Another example would be a finding favoring single-sex in a 10th-grade sample and coeducation in a 12th-grade sample for the same outcome variable within a single study. If a study had findings that were both pro-SS and null, it was coded a pro-SS; if the study had findings that were both pro-CE and null, it was coded as pro-CE. Only studies with findings favoring both single-sex and coeducation were coded as mixed. It should also be kept in mind that some researchers evaluated multiple outcome variables in their research; therefore, it is possible that a single published study would yield information that appears in multiple rows of the Summary Table.

Implications of Review

Summary of Findings in Each Domain

Concurrent, quantifiable academic accomplishments

In general, most studies reported positive effects for SS schools on all-subject achievement tests. Studies examining performance on mathematics, science, English, and social studies achievement tests found similar findings with one caveat. Within each of these subject-specific categories, roughly a third of all studies reported findings favoring SS schools, with the remainder of the studies split between null and mixed results. This minimal to medium support for SS schooling applies to both males and females and in studies pertaining to both elementary and high schools. The overall picture is split between positive findings for SS schooling and no differences or null findings, with little support for CE schooling. The one study that found advantages for CE schooling found advantages for white females but not for Asian or black females. Males continue to be underrepresented in this realm of research.

Long-term, quantifiable academic accomplishment

As opposed to concurrent indicators of academic achievement, any positive effects of SS schooling on longer-term indicators of academic achievement are not readily apparent. No differences were found for postsecondary test scores, college graduation rates, or graduate school attendance rates. However, all the findings in this domain came from a pair of studies, indicating the lack of high-quality research on these important criteria. Although some studies favor single-sex education in the case of postsecondary test scores, there is a dearth of recent studies using controls. There has been a similar lack of research on other potential criteria in this domain, such as college grade point average, meritorious scholarships or funding attained, postgraduate licensure test scores, and any career achievement that could ostensibly be tied to quality of schooling.

Concurrent, quantifiable indicators of individual student adaptation and socioemotional development

This category includes a range of outcomes that are not easily grouped together, and the results are mixed. Regarding self-concept and locus of control, the studies are split between those showing positive effects for SS schooling and those showing no differences. In the case of self-esteem, a third of the studies supported CE schooling while half found no difference. Given a recent extensive review concluding that self-esteem's relationship to school success, occupational success, better relationships, leadership, delinquent behavior, and other desirable outcomes is modest to nonexistent, the implications of findings regarding self-esteem appear complementary. Furthermore, CE schooling only had a positive impact on the self-esteem of males.

Findings regarding school track and subject preferences were mixed, with the overall weight of the findings lying somewhere between pro-SS findings and no differences. A majority of studies favored SS schools on the outcome of higher educational aspirations, as evidenced by SS students showing more interest in and taking more difficult courses. SS schools fostered higher educational and career aspirations for girls. More studies emphasized the positive effect of SS schools on career aspirations than CE schools for boys, but evidence regarding their educational aspirations was mixed. A category called "attitudes toward school" showing mixed results was actually a combination of single studies using somewhat different outcome variables, thus reducing the meaningfulness of the category. In terms of actual behaviors, a few studies focused on delinquency, reporting differences in favor of SS schools that were moderated by individual developmental differences. What is lacking is a conceptual framework to tie together the myriad academic-attitude outcome measures used in this realm so that studies will be more directly comparable.

Long-term, quantifiable indicators of individual student adaptation and socioemotional development

The outcomes in this domain generally do not appear in more than one or two studies that made it to Phase III review. Therefore, one must be cautious in generalizing from these results. Having said that, the results still suggest the potential that SS schooling could be associated with a number of post-high school, long-term positive outcomes. These include postsecondary success or participation in collegiate activities while maintaining full-time enrollment for a four-year period, reduced unemployment (males and females), reduced propensity to drop out of high school (males and females), the choice of a nontraditional college major (for females), and political activism (for females). The sole exception is eating disorders; one study found more SS students to have eating disorders than CE students.

Procedural (e.g., classroom treatment) and outcome measures of gender inequity

This question could not be addressed because of a lack of any quantitative studies that used gender equity as an outcome variable at the school level. Any studies that compared SS and CE classrooms within a CE school were outside the purview of this study and were not reviewed.

Perceptual measures of the school climate or culture that may impact performance

This category includes a number of disparate, single-study results. One of the two studies addressing leadership opportunities found more opportunities for both males and females in SS schools; however, the statistical significance of this finding depended on what other variables had been controlled for. The other found that both males and females in SS schools put more value on grades and leadership and less on attractiveness and money. However, there remains a dearth of high-quality empirical studies using this class of outcome variables as criteria.

A final category of outcomes examined as a subset of culture was the realm of subjective satisfaction of students, parents, and teachers with the school environment. The one study in this review that found the social environment more appealing in CE schools is a good case in point in that the same study found that SS students are more interested in grades and leadership and less interested in money and looks. Some qualitative studies have looked at why certain parents prefer SS schooling, and studies in other cultures have found mixed results regarding teacher satisfaction with CE versus SS schooling. However, no empirical studies comparing current parental satisfaction in equivalent SS and CE schools were available for review using the stated guidelines. There remains a lack of research both on this class of criteria and on the relationship of subjective satisfaction to other more critical criteria.

Expected Outcomes Not Seen in the Review

Teenage pregnancy, college performance, differential treatment by teachers, parental satisfaction, bullying in school, and teacher satisfaction were among the many outcomes that we expected to see in the review or that should be addressed but were not found in any included study.

General Trends

A few trends are apparent across all outcomes. The preponderance of studies in areas such as academic accomplishment (both concurrent and long term) and adaptation or socioemotional development (both concurrent and long term) yields results lending support to SS schooling. A limited number of studies throughout the review provide evidence favoring CE schooling. It is more common to come across studies that report no differences between SS and CE schooling than to find outcomes with support for the superiority of CE. In terms of outcomes that may be of most interest to the primary stakeholders (students and their parents), such as academic achievement test scores, self-concept, and long-term indicators of success, there is a degree of support for SS schooling.

The overwhelming majority of studies employ high school students, with a small minority using elementary school students. The preponderance of SS research has been conducted in Catholic SS schools in which students are separated by sex only when entering adolescence. Therefore, opportunities to study SS elementary or middle schools in either the public or private sector have been limited.

There is also a pronounced tendency to study girls' schools more than boys' schools: 76 studies compared SS and CE girls, and 20 of those focused exclusively on girls. Of those 20, 18 were split evenly between support for SS schooling and no differences (nine pro-SS and nine no differences). The other two studies resulted in findings supporting CE schooling. SS and CE schooling for boys was compared in 55 studies, of which only three were studies exclusively devoted to boys' schools.

There is a dearth of quality studies (i.e., randomized experiments or correlational studies with adequate statistical controls) across all outcomes. Even using the more relaxed criterion of allowing correlational studies, each outcome has only limited candidate studies. Too few researchers report descriptive statistics or effect sizes. Mathematics achievement test scores, English achievement test scores, and school subject preference were the only outcomes to have 10 or more qualifying studies. Even within these three categories, the studies differ in the criteria they use and the statistical controls they use to compare SS and CE schooling. This somewhat limits the arguments that can be built and extended from this quantitative review and renders it nearly impossible to conduct a meta-analysis on any outcome area. Many of the remaining studies have other conceptual or interpretive flaws. Many of the studies lacked well-developed hypotheses, and the hypotheses were often not linked directly to the outcomes being studied.

The list of outcomes of interest needs to be expanded in future research and defined more clearly. For example, outcomes such as teenage pregnancy and bullying in school did not appear in a single study of sufficient quality to be reviewed. Other outcomes that are implicit in arguments for and against SS schooling need to be addressed explicitly. These include work-related long-term outcomes such as job performance, leadership performance, mixed-sex work team performance, performance and leadership in volunteer associations, job involvement, and organizational commitment. Few studies address important moderators, that is, variables that may have differential effects for single-sex schooling. For example, a number of authors have proposed that SS schools are particularly effective for students of lower socioeconomic status and perhaps specifically for those who are members of minority or disadvantaged communities. Unfortunately, only three studies addressed this moderator.

This review should not be interpreted as a condemnation of the work of the dedicated researchers who have chosen to study SS-CE differences, as they may not have been in a position to conduct a randomized experiment on this topic. Such a study has yet to be conducted. However, it could be argued that instead of trying to conduct only all-or-nothing studies of whether SS schooling is better or worse than CE schooling, more careful specification of hypotheses and direct linkage of hypotheses to specific outcomes may show ways to also conduct smaller studies that prove whether certain aspects of SS or CE schooling are beneficial.

Finally, there are limits to what a systematic review can accomplish when an intervention is being judged by multiple criteria and all stakeholders do not share the hierarchy of these criteria. Some issues cannot be resolved by any type of research, even randomized experiments, because they involve issues of philosophy and worldview and represent the relative priorities of dueling stakeholders. There is no way to resolve whether an outcome that is important to one stakeholder group, such as parents, students, civil libertarians, and feminists on both sides of the issue, should be accorded more weight than an outcome valued by another group. What is possible is to separate out fact in the form of evidence from fiction by converting as many claims as possible to testable hypotheses and performing the necessary research. In this way, the two parallel debates can be separated from each other. "Does SS schooling benefit or harm the students, and in what ways?" can be separated from "Is it worth it for society regardless of the benefits or costs?" with each debated on its own merits.

These general implications of the review provide a stepping-stone for future research through the continuation of quality research on extant outcomes, the refinement of methodology, better statistical reporting, and the expansion of the theoretical domain. If heeded, these implications can improve the generalizations made about single-sex schooling and coeducation.

BLOG: The Impact of Single-Sex Education on Educational and Personal Outcomes

By Caitlin McCarey. Wellesley College

This review assesses the impact of single-sex education programs on educational and personal outcomes of lower, middle, and high school aged students. This discussion is guided by two research questions, grounded within an economic framework. First, are single-sex education programs more beneficial for students than co-educational (co-ed) programs? Second, are the effects of single-sex education programs heterogeneous for different groups (boys vs. girls, majority vs. minority students, and high vs. low income students)? Quality randomized controlled trials have only recently been utilized to answer these questions. The review concludes that single-sex schools range from “equally as effective” to “more effective” than co-ed schools along measures of students’ personal and academic outcomes. Therefore, we recommend a program of increased school choice where families can choose between single-sex and co-ed schools.

Advocates of single-sex education trumpet the many benefits of learning in a single-sex environment: girls become more confident in their abilities, boys embrace their emotions, classroom disruptions are reduced, and educational outcomes are increased for everyone (Hayes et. al., 2001; Hughes, 2007). Opponents of single-sex education, however, claim that segregating the sexes vindicates pseudoscience and will be outright harmful because it encourages hyper-sexuality and reinforces the gender binary (Eliot, 2007; Halpern et. al., 2011; Goodkind, 2012). Until recently, the dearth of high quality randomized controlled trials allowed the propagation of misinformation regarding single-sex education.

This paper will examine two meta-analyses that conducted a review of the single-sex education literature within the past decade. Very recent studies, including randomized controlled trials in Korea and random experiments in the UK, will then be described and analyzed to address holes in these meta-analyses. Overall, this paper will conclude that while approximately two-thirds of studies find no difference between single-sex and co-ed schools, approximately one-third of studies find advantages to attending a single-sex school. To my knowledge, no studies have found that single-sex schools harm students or that co-ed schools benefit students. The literature includes studies on all-boys and all-girls environments in lower, middle, and high schools.

This literature review will proceed in several steps. First, I will describe the importance of researching single-sex schools. Second, I will describe the economic theory behind the general equilibrium that arises after the introduction of single-sex schools to a school district. This discussion yields the following two research questions: (1) Are single-sex education programs more beneficial for students than co-educational programs? (2) Are the effects of single-sex programs heterogeneous for different groups (boys vs. girls, majority vs. minority students, and high vs. low-income students)? Third, I will provide an overview of the empirical evidence of these policy questions. Fourth, I will examine the causal mechanisms that may have lead to these results. Fifth, I will assess the external validity of the studies discussed in the third section. Sixth, I will briefly discuss the cost-effectiveness of single-sex education programs. Finally, I will provide recommendations for future experiments and conclude by answering the research questions.

Section One: The Importance of Single-Sex Education

It has been shown that girls and boys enter kindergarten with the same aptitudes and same abilities in all subjects—including science and math. However, over the six years of elementary school, girls lose two-tenths of one standard deviation in test scores relative to their male peers (Fryer & Levitt, 2009). This is half of the black-white test score gap over the same period (Fryer & Levitt, 2009). If social conditioning or societal attitudes about gender roles are holding girls back in the classroom, single-sex schools may present a solution. After all, an individual’s education level impacts her likelihood of attending college, and choice of major and success in college will influence her choice of career and future earnings. There is great inequity in the workplace. The gender wage gap persists across all industries, and men are still much more likely than women to earn a degree in business and STEM.

Therefore, increasing women’s educational achievement is a key goal for the United States and the world. Higher levels of education have been linked with a plethora of desirable characteristics, such as lower infant mortality rates, lower teen birth rates, higher levels of economic output, higher wages, and greater gender equality. Especially in countries were co-ed schooling is culturally or religiously undesirable, single-sex schools may provide the solution to increasing overall education levels for girls and women. If single-sex schools increase girls’ competitiveness and confidence levels in their abilities, single-sex schools may contribute to the reduction of both the achievement-gap and the gender wage gap in Westernized countries like the United States.

After the No Child Left Behind (NCLB) Act was modified by Congress in 2006, single-sex schools were no longer considered a violation of Title IX. This led to a 4,400% increase in the number of single-sex classrooms in the United States by 2010 (Booth et. al., 2013). It is important for U.S. policymakers to study single-sex environments (both single-sex classes and single-sex schools) as more and more students are opting to learn in them. Currently in the US, single-sex schools are seen as the purview of the wealthy or the religious, but this may change as more and more studies on the benefits of single-sex schools are released. In order to stay on top of these trends and to ensure the best educational programs for its students, the U.S. must study these programs rigorously.

Section Two: Economic Theory and Intuition

It is not clear how the addition of single-sex classrooms or single-sex schools would affect education production in a general equilibrium. This is because single-sex education is not universally desired. There are many families who, due to misinformation or personal reasons, may not want their children to attend a single-sex school. For example, while many families view single-sex schools as empowering and cutting-edge, an equal or larger number may view them as outdated anachronisms of a more sexist American educational system. Additionally, if single-sex schools are private or religious schools—as they overwhelmingly are in the U.S.—families could have additional reasons to select or not select into a single-sex school. These reasons could include both location and income constraints. Therefore, while the addition of a single-sex school to a school district may be most analogous to the addition of a private school in terms of the general equilibrium effects, we cannot be certain this is an accurate comparison.

Let us proceed with the assumption that families prefer single-sex schools is over co-ed schools. This means, if a single-sex school enters a school district, most families would prefer to send their children to the single-sex school instead of the public co-ed schools. Under this assumption, the entrance of a single-sex school to a school district will function as an exogenous shock on the education system. The equilibrium result could be increased competition as the public schools attempt to compete with the single-sex school. This could lead to an increase in the resources and average test scores in the public schools, improving the delivery of education services. However, there could also be public school decay as the smartest, wealthiest students leave the public school system to attend the single-sex school.

Moreover, the addition of a new school would drive up the demand for teachers, leading either to a salary increase or the departure of the best teachers from the lower-paying sector to the higher-paying sector (the higher-paying school will often be the co-ed public school). The effect could be reversed, however, if teachers prefer teaching in single-sex environments or if the single-sex school is associated with smaller class sizes, brighter students, wealthier parents, a certain racial composition, or other characteristics upon which teachers make their educational decisions.

If the single-sex school will only accept boys or only accept girls, this could lead to a gender imbalance in the public schools. If having more girls in a classroom is beneficial for all students and having more boys is detrimental, there could be additional effects on the students in the public school. Finally, if families prefer single-sex schools to co-ed schools, families who derive higher utility from sending their children to such schools could move into the school district. This could drive home prices higher, which could benefit the public school system if they are funded mainly from property taxes. It is unlikely families would flee the district if they did not have a preference for single-sex schooling. Therefore, there could be important general equilibrium concerns for school districts contemplating the addition of a single-sex school.

Section Three: Causal Evidence

It is difficult to quantify the effects of single-sex classrooms and single-sex schools for several reasons. First, students self select into these environments. That is, students with nonrandom characteristics are more likely to choose to attend single-sex schools. Family characteristics like income or religion could affect this choice along the extensive margin (insofar as many single-sex schools are Catholic schools or private schools), while the student’s personal characteristics and abilities could affect the decision along the intensive margin. Additionally, single-sex schools are overwhelmingly private schools.

The effects of learning in a private school (which traditionally has smaller class sizes and more resources than public schools) may obscure the true effect of learning in a single-sex environment. It is difficult to tease out these two effects. Therefore, the studies with the highest internal validity will involve randomized controlled experiments that capitalize on situations where students are randomly assigned to single-sex vs. co-ed schools or classrooms, or where curricula, teachers, and resources are fixed across classrooms and schools. Several studies meet these criteria; they will be discussed late in this section. But first, the results of two meta-analyses will be examined to provide an overview of the single-sex schooling landscape.

The first meta-analysis I will review was conducted by economists Erin Pahlke, Janet Shibley and Carlie Allison (2014). They analyzed data from over 180 studies conducted in 21 nations on the effects of single-sex schooling on academic outcomes and student characteristics (such as confidence, competitiveness, etc). In order for a study to be included in their meta-analysis, it had to 1) contain quantitative data on student outcomes, 2) assess K-12 schooling, 3) measure personal or academic outcomes, 4) include separate treatment and control groups (Pahlke, Shibley, & Allison, 2014). Out of almost 2,500 studies regarding single-sex education, only 184 studies found to meet these criteria.

These 184 studies were then labeled as “controlled” or “uncontrolled” studies. A controlled study used random assignment of students to single-sex or co-ed classes/schools or controlled for family characteristics like socio-economic status. Uncontrolled studies had no controls for selection effects. Therefore, the controlled studies possess the strongest research methods. Table 1 is a visual representation of the results obtained by the 57 controlled studies; it is modified from a table of all 184 studies in Pahlke, Shibley, & Allison (2014).   

McCarey_table_2017

Pahlke et al. (2014) separated the results of their meta-analysis by effect category (i.e. academic outcomes, personal outcomes, and so on), so that is how I will proceed in my review. Due to their weaker research design, uncontrolled studies will not be examined here. The results presented here are average weighted effects, which gives greater weight to studies with larger sample sizes. First, the authors examine the effects of single-sex education on students’ math scores. The overall effect of single-sex education on students’ math scores was positive but very small (Pahlke, Shibley, & Allison, 2014). There were larger effects for male students than for female students, but because the positive estimates are both so small, the authors conclude there is a negligible effect of single-sex schooling on student math scores. There was some inter-group heterogeneity: girls in middle school derived modest improvements in math scores from placement in single-sex environments (Pahlke, Shibley, & Allison, 2014).

Next, the authors examine the effect of single-sex classes and schools on students’ mathematics attitudes, concluding that there is no effect for either male or female students (Pahlke, Shibley, & Allison, 2014). There was no weighted effect of single-sex schooling on students’ performance in science, and there were not sufficient studies to conduct an analysis on the change in students’ scientific attitudes. The effects of single-sex schooling on verbal performance were also close to zero (Pahlke, Shibley, & Allison, 2014). In terms of general school achievement, the difference in female achievement was small but positive; there were not enough studies to measure the effects on male students (Pahlke, Shibley, & Allison, 2014).

Additionally, there were not enough studies to determine the effects on students’ attitudes towards general education. The weighted effect of single-sex on gender attitudes, however, implied that female students in co-ed schools were much more likely to endorse gender stereotypes than single-sex cohorts. However, the authors urge caution in interpreting this effect due to variance between the weighted and unweighted effects. There were insufficient studies to measure the effects of single-sex on male stereotypes. There was no difference in student aspirations across single-sex and co-ed schools.

Overall, the authors conclude that there are only trivial advantages to attending a single-sex school versus a co-ed school along important measures like student achievement and student attitudes (Pahlke, Shibley, & Allison, 2014). The authors attribute this dissonance between the perceptions of single-sex schooling benefits and these studies to the dearth of rigorous study design. They posit that many studies do not control for selection effects and student characteristics, which biases public opinion regarding the results. Additionally, the authors conclude that there are not heterogeneous affects by gender, socio-economic status, or age. These results contradict studies that have found large positive effects of single-sex schooling for younger girls. Therefore, they conclude that there is no evidence that single-sex schools offer educational and personal advantages to either male or female students.

A second meta-analysis was conducted by Fred Mael, et al. (2005) at the behest of the Department of Education. This study uses the evaluation standards of the Campbell Collaboration (CC) and the What Works Clearinghouse (WWC) to evaluate studies on the effects of single-sex education. Overall, they state their results are equivocal—there is no evidence of either benefit or harm from attending a single-sex school. To be included in this meta-analysis, the studies had to involve students enrolled full-time in elementary, middle, or high schools in Westernized or English-speaking countries. As with Pahlke’s meta-analysis, no studies involving college students were included. The condition on Westernized countries was added to ensure the results were applicable to the U.S. education sector.

When the strict guidelines of the WWC were applied to the single-sex education literature—that is, that all studies other than randomized controlled trials, quasi-experimental designs with matching, or regression discontinuity designs be excluded—no studies remained for analysis. Therefore, Mael et al. modified the WWC standards and included all correlational studies utilizing robust statistical controls for student ability, family SES, and school resources (Mael et al., 2005). There were 40 quantitative studies that met the modified criteria. As Mael’s meta-analysis was published before Pahlke’s, all of the 40 studies examined by Mael are included in Table 1, which is based off of a summary table appearing in Pahlke et. al. (2014). Mael’s results are either pro-single-sex schools or show no difference between outcomes among graduates of single-sex and co-ed schools.

The results of Mael et al.’s study are organized along several classifications. First, they state that most studies report either positive effects or no effects of single-sex schools on students’ academic achievement. Specifically, of studies that examined students’ performance on mathematics, science, English, and social sciences tests, roughly a third found that students in single-sex environments outperformed students in co-ed environments (Mael et al., 2005). The remaining two-thirds of studies found no difference in academic performance. These results argue moderately in favor of single sex schools. Next, the authors state that long-term measures of student success (such as college attendance or graduation rates) cannot be directly attributable to single-sex schools. Recent research conducted in Korea has found positive effects of single-sex schools on college attendance (Park, Behrman, & Choi, 2012b). These studies will be discussed later.

The next category of results that Mael et al. analyze involves student socioemotional development. Overall, the results are mixed. Interestingly, a third of studies regarding self-esteem found positive effects for co-ed schools, while the remainder showed no preference. These positive effects were only for male students. Additionally, the authors state that a majority of studies found that single-sex schools had a positive effect on the higher educational aspirations of female students. There were positive effects on career aspirations for boys at single-sex schools, but not for educational aspirations (Park, Behrman, & Choi, 2012b). The authors write that there were not enough studies to issue blanket statements regarding the effects of single-sex schools on overall gender inequity, school climate, unemployment, graduation rates, mental health, or parent and student satisfaction. Overall, Mael et al. agree with Pahlke et al. that there is a dearth of quality, randomized studies with robust statistical controls (Mael et al., 2005).

Since the publication of these two meta-analyses, several studies with more rigorous experimental designs have been written. These have studied the effects of random assignment of students in metropolitan areas to co-ed or single-sex middle and high schools in South Korea (Park, Behrman, & Choi, 2012a; Park, Behrman, & Choi, 2012b; Lee, Niederle, & Kang 2014a; Lee, et. al, 2014b) or the random assignment of students to co-ed vs. single-sex classrooms within co-ed universities (Booth, 2013; Booth and Nolen, 2012; Eisenkopf, 2014). While many of these studies found positive effects of single-sex schooling, a non-inconsequential number found no difference between single-sex and co-ed schools. However, based on our prior analysis of the Pahlke and Mael meta-analyses, this is not surprising. These studies will be examined below.

The Korean studies take advantage of a random assignment program that was implemented in 1974 and occurs in Seoul and the six largest metropolitan centers in Korea. Students are randomly assigned via a lottery system to either co-ed or single-sex middle and high schools within their district; almost 75% of Korean high school students attend schools that are included in the lottery system (the remaining 25% attend vocational high schools). Importantly, both public and private schools partake in this lottery system and cannot reject the students assigned to them.

While non-compliance in such a program would traditionally be a key concern, Park et a. argue the potential bias from non-compliance and attrition are minimal. This is because the only way for students to transfer to another school is to move to a new school district. In this new district, students would be reassigned to a new school based on the same random lottery, thereby minimizing or negating the benefits of moving in the first place. Additionally, Park et al. showed that only a very small number of households do move during the relevant timing of high school, indicating that non-compliance is not biasing the estimates (Park, Behrman, & Choi, 2012a).

The Korean studies measure the effect of single-sex schools on student test scores, college entrance exam scores, rates of college attendance, choice of college major and career, and student competitiveness. Park, Behrman, and Choi conclude that attending a single-sex high school is associated with higher average scores on Korean and English tests, higher rates of four-year college attendance, and lower rates of two-year college attendance for both male and female students (Park, Behrman, & Choi, 2012b). The increases in test scores are large (7% to 15% of one standard deviation), although not all are statistically significant.

Park, Behrman, & Choi (2012b) also found that male and female students at single-sex schools are more likely to attend four year colleges, and less likely to attend two year colleges, than co-ed cohorts. The differences in college attendance are quite substantial—.5 standard deviations for girls and .8 standard deviations for boys (Park, Behrman, & Choi, 2012b). These results are robust to controls for school-level variables such as teacher quality, the student-teacher ratio, and the proportion of students receiving lunch support, and whether the single-sex schools are public or private (Park, Behrman, & Choi, 2012b).

In a second study of the Korean high schools, Park, Behrman, and Choi obtain additional administrative data and longitudinal survey data on students’ college entrance exam math scores and choice of a STEM college major two years after enrolling in college. Park et al. found that both male and female students attending single-sex schools outperformed their co-ed counterparts on national standardized math tests. The positive effects of attending a single-sex high school were quite large (ranging from 7% to 25% of one standard deviation, and were larger for boys than for girls. Interestingly, despite the higher math test scores, female students at single-sex high schools were no more likely to major in STEM in college than female students from co-ed high schools. However, boys from single-sex high schools were both more likely to choose a STEM major and more likely to report a high interest in STEM subjects. These patterns held in both Seoul and non-Seoul schools.

There are several internal validity concerns that arise in studies that measure the effects of single-sex schools in Korea. First, after concerns arose over lack of school choice, some districts outside the capital modified the random lottery to allow students to list two or three schools are their “preferred” choice. In each non-Seoul school, 30-40% of their enrolled students were randomly selected from the students who had labeled that school one of their preferred schools, while the remaining 60-70% of students were determined completely at random (Park, Behrman, & Choi, 2012a). Due to this policy modification, some of the students in each school are able to self-select into that school. This introduces selection bias that may prejudice the results. However, after comparing the characteristics of the Seoul and non-Seoul cohorts, Park et al. found that students at single-sex schools and co-ed schools had similar levels of academic achievement socio-economic backgrounds.

A second internal validity concern for the Korean studies is that public and private school teachers are subject to different licensing requirements and recruitment incentives. For example, public school teachers have to take additional teaching exams and are subject to school rotations every 4-5 years. As Park et al., states, this may lead to differences in teacher-related characteristics across public and private schools. Finally, the majority of single-sex schools in Korea are private, while most of the co-ed schools are public. This means that in addition to varying along the lines of gender composition, single-sex schools and co-ed schools could also vary along other important characteristics such as teacher quality or characteristics.

Other Korean studies have taken advantage of the random assignment of middle school students to co-ed middle schools, co-ed middle schools with single-sex classrooms, or single-sex schools (Lee et al, 2014; Lee, Niederle, & Kang, 2014). Middle school students in Korea are assigned to their schools based on a similarly random procedure as governs high school assignment, except no middle school students can submit school preferences. Compliance is high, because the only way to change to another school is to move to another school district and re-enter that district’s school lottery. These studies aim to counteract some of the biases that may be influencing the high school studies. These studies have high internal validity because students are assigned to classrooms in a process that equalizes prior academic achievement, and there is strict adherence to a nationally designed curriculum. Additionally, all schools receive equal funding, which removes concerns over differences in resources.

Lee et al. (2014) conclude that male students attending single-sex schools outperform male students in co-ed classes by .15 standard deviations. They state that this improvement was driven by increases in male students’ effort and time spent studying. Interestingly, male students in single-sex classes within co-ed schools perform .10 standard deviations below male students in co-ed classes. Lee et al. concludes that this achievement gap between boys in co-ed schools but single-sex classrooms and boys in co-ed schools and co-ed classrooms is due to the change in gender composition. There were no differences in test scores across the female students in co-ed vs. single-sex classes. They offer no explanation for this result.

A final study uses the random assignment of Korean students to middle schools to measure the effect of the gender composition of classrooms on students’ willingness to participate in competitive activities. Lee, Niederle, and Kang (2014) conclude that, contrary to popular belief, the gender gap in competitiveness is not reduced by single-sex schooling. This result is robust to controls for student achievement and parent characteristics. To measure competitiveness, the authors created various competitions where students competed against each other to solve arithmetic problems. While there are no differences in student performance on the tasks, female students from single-sex schools are 15 percentage points less likely to opt into a tournament-style (i.e. highly competitive) game than are boys in co-ed schools (Lee, Niederle, & Kang, 2014). Girls in co-ed middle schools are only 8 percentage points less likely to choose to compete in the tournament (Lee, Niederle, & Kang, 2014). Several randomized experiments conducted at a University in the United Kingdom disagree with this conclusion.

Additional studies have conducted randomized experiments on students at co-ed universities. Booth et al (2013) designed an experiment where all first year economics students at the University of Essex in the United Kingdom were sorted into either single-sex or co-ed discussion sessions for their ECON 101 classes. The classes were year-long and taught for two hours every week by one professor in a lecture hall, supplemented by one hour of instruction per week taught by teaching assistants (TA). Students were randomly assigned to co-ed, all-boy, or all-girl TA classes. The co-ed and single-sex classes were the same on almost all observable characteristics, and there was no attrition because students were not allowed to switch classes.

Booth et al. found that female students in the single-sex classes were 7.5% more likely to pass their first year courses and scored 10% higher in their required second year economics courses than their female peers assigned to the co-ed class. Additionally, women in single-sex classes were 9.3 percentage points more likely to complete optional homework assignments and nearly 6 percentage points more likely to attend classes. However, women in the single-sex classes were no more likely to take technical classes (econometrics or advanced math courses) in later years than their counterparts. There was no affect on the passage rates or test scores of male economics students.

A second study conducted concomitantly by Booth et al. (2013) with the students at Essex University included an experiment designed to test students’ risk tolerance. They administered tests to all economics students in the first week and the eighth week of class. While female students were more risk averse than male students at both times, female students in the single-sex TA-classes were significantly more likely to exhibit risk-seeking behavior in the 8 th week than female students in the co-ed TA-classes. The magnitude of this effect was substantial. There was no change in risk aversion for male students. These results were robust to the inclusion of controls for IQ, academic ability, and personal characteristics. A second but comparable study by Booth and Nolen (2012) found that middle school girls who attended public single-sex schools exhibited similar levels risk tolerance to boys from co-ed schools in controlled experiments. Both of these studies disagree with the results of Lee, Niederle, & Kang (2014) that attending single-sex schools does not affect the competitiveness of female students.

Section Four: Evidence on Causal Mechanisms

In order to design the most effective education policy, it is imperative that we understand why single-sex schools might produce different outcomes than co-ed schools. A plethora of possible mechanisms have been discussed in the literature. These mechanisms include: 1) tracking; 2) peer effects; 3) decreased distractions during class; 4) increased number of same gender role models; 5) differences in curriculum/classroom organization; 6) differences in funding/resources; 7) reduction in stereotype threat. Each of these mechanisms will be discussed, although the relative weight and importance of each mechanism cannot be determined due to the difficulty of separating their effects.

The first explanation for why single-sex schools could effect improvement along academic dimensions is the model of student tracking. This model posits the idea that students will perform better if they are surrounded by peers with similar academic abilities. For example, Duflo et. al. (2011) found that sorting students into elementary school classes based on ability caused both high-achieving and low-achieving students to perform better on end of the year tests. If students have similar abilities—say, in an honors class where all students are above average—the teacher will be able to teach to the median level of achievement, which will be a satisfactory level for the majority of students. In a class with a large distribution of academic achievement may lead teachers to teach to the right tail of the achievement distribution. If teachers are advancing through the material too quickly for the majority of students in the class, the removal of the top students may allow the teacher to slow down, and therefore teach at a more appropriate level.

If female students are less likely to be in the right tail, isolating students by gender may reduce the variance in female student achievement and allow a tracking mechanism to improve student scores. Alternately, if female students are more likely to be the top performers in a class, removing male students may allow the pace of an all-female class to accelerate. However, Booth et. al (2013) reject tracking as the mechanism through which single-sex schools benefit students. They demonstrate that both the distribution and standard deviation of ability are the same for both female-only and male-only classes. That is, both male and female students have similar ability distributions. This implies there will be no tracking by ability if one segregates classes based on gender. Therefore, it seems unlikely that tracking is the cause of the benefits of single-sex schooling.

A second mechanism through which single-sex schools could benefit students is peer effects. Peer effects include any way in which a student’s classmates affect his or her behavior, such as through peer instruction, knowledge spillovers, influence on classroom standards and disciplinary behaviors, and overall classroom environment (Hoxby, 2000). Often it is very difficult to isolate various peer effects. There are some ideas how peer effects could be exerting influence on students in single-sex environments. First, it is traditionally stated that students in single-sex environments care less about superficial qualities like looks or popularity and spend more time focusing on schoolwork.

Lee et. al. found that female Korean middle school students in single-sex schools were more likely to report that their peers worked hard than female students in single-sex classes within co-ed schools, and that male students at single-sex schools spent more time studying than male students at co-ed schools (Lee et. al., 2014, Park et. al., 2012b). There could also be peer effects from increasing the number of female students in a class. Several studies have found that both male and female students perform better as the fraction of female students rises (Lavy and Schlosser, 2011; Hoxby, 2000) and that female students complete more optional assignments when assigned to single-sex classes (Booth et. al., 2013). Therefore, it seems that peer effects could be one potential mechanism through which single-sex increase student outcomes.

A third mechanism explaining these benefits could be that female students in single-sex environments may be subject to fewer distractions, disturbances, interruptions, or violent episodes than female students in co-ed classes. This could be because young boys are socialized to respond differently in academic environments, or because of genetic differences in boys’ brain chemistry. Whatever the cause, several studies have found that decreasing the number of boys in a classroom increases both boys’ and girls’ achievement. For example, when Lavy and Schlosser (2011) concluded that increasing the fraction of female students in a classroom raised overall academic performance of all students, they concluded that the mechanism through which this effect operated was a reduction in classroom disruption and violence, and not due to spillover effects (Lavy and Schlosser, 2011). They found no change in individual students’ behavior, implying that the positive effects operated through a compositional change, i.e. gender peer effects. Hughes (2007) also found that the gains from single-sex schooling come in part from decreased classroom disturbances and greater equity of opportunity for female students.

A fourth mechanism could be the increased presence of same-gender role models at single-sex schools. It has been shown that single-sex schools employ a greater number of same-sex teachers—all-boys schools employ more male teachers than co-ed schools, while all-girls schools employ more female teachers (Riordan, 1990). Studies have shown that female high school students achieve higher levels of schooling if their co-ed high schools have a higher fraction of female professional staff. If students learn more effectively and efficiently from teachers of their own gender, as has been posited, this effect could be one of the reasons for increased performance at single-sex schools.

While the economics of education literature has shown that minority students perform better with a minority teacher (Dee, 2004), the results are less conclusive regarding gender. For example, Park et. al. (2012b) proposed that one of the explanations for the vast gains in English and Korean test scores experienced by both boys and girls in single-sex schools could be attributed to the higher numbers of same-sex teachers. They cite research that shows higher fraction of female teachers could counteract research that shows that boys receive higher levels of encouragement and reinforcement, especially in math and sciences, than female students (Park et. al., 2012b). However, Lee et. al. (2012) concluded that while single-sex schools were better for both male and female students, this effect was not driven by the gender composition of the schools. More research must be conducted on this subject.

I will combine the discussion of the next two mechanisms, differences in classroom organization and funding levels, because they are so interrelated. In the US, most single-sex schools are private schools, and most co-ed schools are public schools. Therefore, it is very important to ensure the results of studies that purport to show the effects of single-sex schools are not mistakenly reporting the effects of being in a private school. Studies that were conducted in Korea, where students are randomly assigned to either single-sex or co-ed middle and high schools, provides guidance in this area. Importantly, all schools in Korea are designed around a strict national curriculum where there are very few opportunities for teachers to modify lessons or teaching methods. Second, schools in Korea are funded through a centralized process, so there are not the vast funding disparities that exist in the U.S. Because these studies found substantial benefits of attending single-sex schools holding these characteristics constant, it appears that the benefits of single-sex schools do not operate through differences in classroom organization or funding levels (Park, Behrman, & Choi, 2012a; Park, Behrman, & Choi, 2012b; Lee, Niederle, & Kang 2014a; Lee, et. al, 2014b).

Finally, the abolition of “stereotype threat” could explain the benefits of single-sex classrooms and schools, especially for female students. Stereotype threat occurs when a student intentionally restricts or modifies their participation in classroom activities to avoid making mistakes that would cause the student to fulfill negative stereotypes about their race, gender, age, etc. For example, female students in math or science classes may ask fewer questions in order to avoid giving the impression that they do not understand the material, because it is a stereotype that girls perform more poorly in math and science classes. Steele, Spencer, & Aronson (2002) found that girls reported more self-confidence in their math abilities after learning math in a single-sex classroom. However, it is extremely difficult to devise an empirical experiment or test that could ascertain whether the abolition of stereotype threat improves female students’ performance. It is also unclear whether single-sex schools for male students would be subject similar mechanisms.

Section Five: External Validity

As I have discussed throughout this paper, self-selection is the greatest threat to both the internal and external validity of studies involving single sex schools. While this bias can be mitigated or even removed through robust experiment design, these sorts of experiments have been few and far between to date. In general, if a study does not control for various school-level and student-level characteristics, we can state with confidence their results are heavily biased by self-selection and student family characteristics. These studies will not be useful as we craft policies regarding single-sex vs. co-ed education.

However, there are several other factors that may affect the external validity of the studies within the single-sex education literature. First, there are the inherent differences across the education systems in non-Western vs. Western countries that make comparisons difficult. In Korea, Thailand, Trinidad and Tobago, and Ireland, single-sex schools are much more common than they are in the US. Single-sex schools in these districts are not subject to increased participation due to their novelty. There are also many differences between these school districts and school districts in the US that makes the application of the results of these studies potentially dubious. For example, differences in teacher training requirements and payment structures may affect the quality of teacher candidates, as well as the methods they use in their classrooms. Finally, none of these countries have the racial tension that exists between minority and majority students in the U.S., so we cannot know for certain how the results of foreign studies would apply to White vs. Black/Latino/Asian students.

Additionally, due to the challenge of conducting randomized experiments with single-sex environments, many of the studies that exist draw on smaller sample sizes. Unlike other fields of economics that can use census data or state-level data, the economics of education literature (and especially single-sex education literature) lack such large-scale, long-term studies. There is as yet no “Tennessee STAR Experiment” for single-sex schools. If the sample sizes of single-sex school studies are not large enough to be representative of the population from which they attempt to sample, the results will be subject to higher variability and error. In the worst-case scenario, the positive effects of single-sex schooling could actually be due to an extremely talented cohort of students.

Finally, many of the studies examining single-sex literature have examined a variety of ways in which these environments may improve student outcomes—from academic to personal outcomes. As there are differing levels of robustness within these experiments, it can be hard to compare studies that also differ in their definition of a successful program. For example, if single-sex classrooms don’t improve student performance but increase girls’ self-confidence, are they still worth it? Additional challenges arise when we attempt to rank or otherwise choose amongst these outcomes: is self-confidence more important than GPA? Are test score increases more powerful than a decrease in classroom distractions? There is no right answer to these questions, but how we choose to answer them will have vast consequences on the studies we conduct and the policies we implement.

Section Six: Cost effectiveness

One of the greatest potential benefits of implementing single-sex education in the US would be its cost: free. No new resources would need to be provided in order to transition co-ed environments to single-sex environments. All we would need to do is reshuffle students into single-sex classrooms within co-ed schools or reassign them to single-sex schools within their school districts. The benefits of single-sex schooling appear even more substantial given the lack of capital required. Other popular educational programs—such as reducing class sizes, improving student-teacher ratios, or implementing improved teacher training programs—would require a substantial upfront and prolonged investment.

Section Seven: Recommendations for Research

As was highlighted in both of the meta-analyses, there is a dearth of rigorous, randomized controlled trials with robust statistical controls that test the effects of single-sex education. In a perfect (hypothetical) world, I would want to design an experiment that utilized random assignment and controlled for selection effects. The experiment would take place on a large scale—perhaps across several states—and occur in the U.S. to maximize its applicability to U.S. education policy. I would want to compare students across various parts of the country, perhaps in New York, Chicago, Florida, Texas, and California, to ensure the results weren’t specific to just one state or one school district. All of the students would be randomly assigned to a treatment (single-sex school) or a control (co-ed school) group.

The treatment group would be split into several further groups: students assigned to single-sex schools from kindergarten-onwards, students assigned to single-sex schools from middle school onwards, and students assigned to single-sex schools from high school onwards. Not only would this allow us to measure the effects of single-sex schools for various age cohorts, but it would also allow us to determine if the duration of exposure to the treatment affected students’ personal characteristics and educational outcomes. Of course, we would make sure all of the groups were balanced across both student characteristics (such as prior academic achievement and personal characteristics) and family characteristics (SES, educational attainment of parents, number of siblings, birth order, neighborhood characteristics). The curriculum and funding levels of all of the schools would be standardized at the national level, as in the Korean studies. A study of this nature would greatly enrich the single-sex schooling literature.

I will conclude by returning to the two research questions asked at the beginning of this literature review: (1) Are single-sex education programs more beneficial for students than co-educational programs? (2) Are the effects of single-sex programs heterogeneous for different groups (boys vs. girls, majority vs. minority students, and high vs. low-income students)? To answer the first question, most studies find no difference between the outcomes of students in single-sex schools and co-ed schools, while some studies find results that favor single-sex schools. No studies have found any negative effects of single-sex education on students.

Due to the paucity of literature addressing the heterogeneous effects of single-sex schools, it is difficult to answer the second question. We cannot conclude that single-sex schools are more or less beneficial for minority vs. majority students or high vs. low-income students because very few studies have attempted to separate out the effects for these groups. However, we can state that while both boys and girls appear to benefit from single-sex schooling, girls may benefit more along academic and personal measures than boys.

These results could be due to peer effects, decreases in classroom distractions, increases in female role models, or the abolition of stereotype threat. It is unlikely that the benefits of single-sex schools are due to tracking, differences in classroom organization, or school funding levels. Overall, I recommend a policy of increased school choice where parents may decide whether to send their children to a single-sex school or a co-ed school.

The Truth About Girls and Boys: Challenging Toxic Stereotypes About Our Children

10 Single-Sex Education, Pros and Cons

This chapter discusses how single-sex education is being deemed as a solution to the high attrition rates in U.S. public schools. Black and Hispanic students perform worse than whites; and students from under-resourced urban school districts perform worse than children from affluent suburban school districts. A number of self-styled educational gurus propose the separation of girls and boys and teaching them according to “their brains” to improve student performance, despite the gender gap being much smaller than racial and social class differences. The study Is Single Gender Schooling Viable in the Public Sector? Lessons From California's Pilot Project recognized that the single-sex setting eliminated social distractions and allowed for better concentration on academics. However, these benefits were undermined since gender stereotypes were often reinforced and stereotypical behaviors were worsened.

Look Into Education

Education leadership: the pros and cons of co-ed vs single-sex education.

September 16th, 2021

education leadership curriculum considerations

The interactions between girls and boys at school influence how women and men relate as equals in the workplace. This is part of the reason why advocates for coeducation say it is a way to socialize young people so they are better prepared for their futures in the workforce and society.

Coeducation and Curricula

Coeducation is the integrated education of males and females at schools and learning facilities. Coeducational schools reflect the diversity of society. Co-ed schools typically offer a curriculum that is accessible to all students and encourages a wide range of learning opportunities. By minimizing gender-linked stereotypes in coursework, educational opportunities can appeal to individuals’ interests, aptitudes, and motivations as opposed to categories like gender.

On the other hand, proponents of single-sex education say students can also flourish academically in single-gender classrooms. The National Association for Single Sex Public Education (NASSPE) asserts that schools that use best practices for gender-specific teaching may be more successful at teaching to boys’ and girls’ strengths.

Research shows the benefits and drawbacks of both models of education. In the past few decades, studies, including a comparison of same-sex and coeducational schools by the U.S. Department of Education, produced mixed results that are not conclusive enough to fully endorse either. Researchers on both sides of the debate continue to work and adapt to current education trends.

Benefits of Co-ed and Single-Gender Formats

Education leaders must evaluate both the merits and obstacles of the different learning environments. Here are common arguments for both coeducation and single-sex education. 

The Case for Co-ed

  • Offers school diversity—students will find it easier to adapt in many different environments.
  • Teaches equality and tolerance—co-ed schools treat students to be tolerant of each other.
  • Promotes socialization—students enrolled in mixed classrooms experience being with members of the opposite sex and are comfortable interacting with each other.
  • Prepares students for the real world—students are exposed to an environment that reflects the larger society.
  • Improves communication skills—studying in co-ed schools can help an individual communicate in different ways.
  • Challenges sexism—a co-ed environment gives students the chance to express themselves and share their views.

The Case for Single-Gender Education

  • Lessons tailored to unique interests and skills—curricula in single-sex classrooms are developed without the influence of social expectations based on gender roles.
  • Ease of forming relationships—camaraderie forms naturally without concerns about cliques and social status. 
  • Minimizes distractions—students focus more on academics and extracurriculars.
  • Removes double standard—girls and boys might be held to obviously different standards in co-ed environments but might not in single-sex schools.
  • Breaking down gender stereotyping—students confidently pursue interests without the assumption of female- and male-dominated subjects.
  • More relaxed environment—there is less of a desire to impress the other gender.

How Aspiring School Leaders Can Maximize Student Success The debate over coeducation vs single-gender education is just one of several educators are facing today. School leaders must incorporate changing attitudes to build effective educational models. William Woods University’s Online Education Specialist in Educational Leadership degree prepares individuals who are often already teachers to be leaders at the school-district level. This Education Specialist degree program features courses like Issues in School Superintendency, which examines the historical perspectives and issues that superintendents face—knowledge that can help educators maximize student success.

Pros and Cons of Single-Sex Education

Pros and Cons of Single-Sex Education

Imagine a typical school classroom and you may conjure up images of boys and girls coexisting, learning alongside each other, raising their hands in equal numbers. However, that’s not usually the case.

According to 2010 data from NCES and the U.S. Census Bureau , from prekindergarten to senior year of high school, male students outnumber female students significantly in public school classrooms: 54 percent to 46 percent in pre-K and 51 percent to 49 percent from first grade to 12th grade.

So with the disproportionate stats in the American classroom, is it beneficial to separate the sexes from each other? Much debate has centered around this topic for years.

The Case for Single-Gender Classrooms

Jefferson Leadership Academies was in the spotlight in 1999 when it became the first public middle school in the United States to have entirely single-gender classes. Its reason? Research showed that girls did better in math and science in all-girl settings. This decision came just a few years after Failing at Fairness: How Our Schools Cheat Girls  — a book that argues that gender bias prevents girls from receiving education equal to that of their male counterparts — was published by two American University professors.

Of course, single-gender education in grade schools didn’t start in 1999, as it existed in the 18th century before coeducation started to trend in the 19th century. However, it picked up steam in the late ’90s, especially when the Supreme Court made a ruling in the United States v. Virginia case involving male-only military college Virginia Military Institute . The conclusion: Single-sex classrooms were only constitutional if comparable resources were available to both genders. In 2006, the No Child Left Behind Act added a provision giving single-sex classrooms and schools the ability to exist as long as they are voluntary. From 1995 to 2006, the number of single-sex schools in the United States rose from 3 to 241.

There are many reasons why people advocate for single-gender classrooms, including less distraction (especially during teenage years when hormones rage), less “ gender intensification ” where coed settings reinforce stereotypes, and more instruction tailored to the unique ways boys and girls learn.

Approximately 30% of Catholic high schools in America are single-sex. See why you might consider a Catholic school, even if you’re not Catholic .

The Case Against Single-Gender Classrooms

In 2007, Jefferson Leadership Academies reversed its same-sex curriculum after issues with disappointing test scores and scheduling conflicts arose. Detractors of same-sex classrooms weren’t surprised since one of the biggest challenges to single-sex classrooms is the lack of concrete evidence that they boost achievement. As Margaret Talbot wrote in her 2012 New Yorker piece , “The evidence wasn’t very good then [the ’90s] for a gap between the genders’ learning styles so significant that it would mandate separate instruction, and it hasn’t gotten any better.”

Plus, another argument against single-gender schools is that the real world doesn’t afford a society where students can work with or interact with one gender over another. Thus, when it comes time for these students to head into the workforce, or even to college, they will face an adjustment period.

Related to college, one of the biggest reasons why single-gender classes popped up in the ’90s was to help women do better in the classroom, but recent statistics show that women attend college in larger numbers, outnumbering men by 14 percent.

In fact, girls are less likely than boys to be held back in American schools, too, so some argue that the effort put into helping girls in the classroom may be counterintuitive when the boys are the ones who aren’t doing as well.

Pro Con
Mixed genders can be a distraction. Studies are inconclusive about how helpful separating genders is.
Single-sex schools break down stereotypes. Eventually, it could be hard for students to assimilate into "mixed gender" society.
Teachers can employ instruction techniques geared toward specific genders. Many teachers may not have the training to employ gender-specific teaching techniques.
Girls mature faster, so potentially boys won't hold them back. Boys mature slower, so potentially girls won't positively influence them.

The Bottom Line

It may seem like a new development in education, but single-sex education is actually a throwback to curriculum systems of yesteryear, from way back before the 19th century. The factor that’s changed is simply the reason behind the implementation, which may continue to evolve as new trends and legislation emerge. It remains to be proven whether single-sex classrooms are beneficial to students.

Advantages And Disadvantages Of Single Gender Education. Here Are Few Points To Consider

Single-gender v/s co-ed schools - the debate has been going on for a long time. We help you decide which is the better choice for your child.

Advantages And Disadvantages Of Single Gender Education

The scenes that you see in a single-gender school are different from those in co-ed schools, but the fun children have remains the same. Of course, there are pros and cons to every decision we make in life and that is why, as parents, we need to know the merits and drawbacks of the school we choose for our kids.

So, what exactly is a single-gender classroom? Imagine walking into a school and finding only girls or boys there. This is what a single-gender school looks like.

But, what was the reason behind setting up single-gender schools? Well, in the 19th century, in Western Europe, only boys were sent to school and girls were educated at home. However, in the USA, at the same time, the idea of sending girls to school was gaining ground. This resulted in the establishment of women's educational institutions. It took a few years longer for the first co-ed school to be inaugurated in Oberlin, Ohio. By the late 20th century, however, many schools that previously catered to a single-gender became co-educational.

Surprisingly, in contrast, women in ancient India enjoyed a high status and there were many women scholars of note. While the Rig Veda mentions the name of female poets, by 800 BCE there were a few women scholars mentioned in the Upanishads as well.

However, the education system in India, and elsewhere, went through several changes over the years and was witness to the popularity of co-ed schools, which mushroomed all over the country. Here, we give you a low-down on the advantages and disadvantages of single-gender schools.

ADVANTAGES OF SINGLE-GENDER SCHOOLS

Reduced distractions:.

With both genders under one roof, there are going to be distractions. The younger boys and girls often end up competing with each other, and older boys and girls getting involved with one another. A single-gender classroom eliminates these distractions in the classroom and children focus more on their studies.

Builds confidence:

While girls are good in some subjects, boys excel in others. When children study in a single-gender classroom, they interact much more confidently and freely and can discuss topics, which they would be otherwise hesitant about. Since all leadership positions are also held by peers of the same gender, children feel empowered and confident about tackling any job.

Eliminates competition between boys and girls:

The reason behind single-gender classrooms is the belief that girls and boys are different neurologically and learn very differently. According to a study 'How The Brain Learns: New And Exciting Findings' presented by Dr Sousa in 2014 ASAIHL Conference in Singapore, boys develop visual, spatial and temporal skills faster than girls and girls acquire spoken language skills faster than boys. In a single-gender school, girls get to explore their skills at their own pace without having to compete with boys and vice versa.

Adapts teaching methods:

While in a co-ed school, it is difficult to cater to everyone's needs, it is easier for teachers to prepare lessons suited to the learning needs of a single-gender class. Usually, boys understand more through physical activities while girls prefer interactions and discussions. According to a study 'With Boys And Girls In Mind' by Michael Gurian and Kathy Stevens published in Educational Leadership in 2004, classrooms based on gender promote different skills and make learning more relatable. The study states 'New PET scan and MRI technologies reveal structural and functional differences in the brains of boys and girls. With more cortical areas devoted to verbal functioning, sensual memory, sitting still, listening, tonality, and mental cross-talk, the complexities of reading and writing come easier to the female brain. Boys lateralize their thinking, need rest states to recharge, and use more cortical areas of their brains for spatial-mechanical functioning. Classrooms that help girls learn will promote gross motor skills, encourage perceptual learning, and use manipulatives to teach math. Boy-friendly classrooms will promote fine motor skills, provide ample space to move around, and make lessons experiential and kinesthetic'.

DISADVANTAGES OF SINGLE-GENDER SCHOOLS

Single-gender interactions:.

While single-gender classrooms provide a relaxed ambiance for children's interaction with their own gender, it is different in the real world, where boys and girls must interact and work with each other. When they are used to interacting only with one gender in school, the awkwardness and newness of the experience make it difficult for boys and girls to interact and converse with each other comfortably.

Creates gender stereotypes:

Studies have shown that single-gender classrooms foster gender stereotypes. Both genders start thinking they are better than the other. "There is strong evidence for negative consequences of segregating by sex -- the collateral damage of segregating by sex," said Lynn S Liben, Professor of Psychology, Human Development and Family Studies, and Education, Penn State in a report 'Sex segregation in schools detrimental to equality', published in Science Daily in 2011.

Lacks diversity:

In single-gender classrooms, the boys or girls do not have the opportunity to listen to perspectives and gain a broader understanding of each other.

Promotes gender disparity:

Single-gender classrooms or schools could make children feel they are superior to the other sex, and that promotes gender disparity. This attitude, in the long run, causes problems when they are working side by side.

"Children usually tend to be shy around each other or are just too curious about each other. In a co-ed, they might fight with each other, but they grow up knowing each other well. This is a healthy way of growing up," says Seetha Kiran, Regional Director, DAV Public School, Safilguda.

CHILD SPEAK

"When you are in an all-boys school, and especially for a long time like I have been, you tend to get shy around girls. It even gets awkward when you get into college, which is mostly co-ed. You don't know what to say or how to behave around the opposite gender. But yes, single-gender schools have their benefits too. There are no distractions and we don't get embarrassed when we are pulled up in class, because we don't feel so conscious."

Aditya Himatsingka,  studies in an all-boys boarding school in Bangalore

PARENT SPEAK:

"Both my boys go to an all-boys school. And I feel there are fewer distractions there. But, I have noticed they are shy around girls. They have certain notions about how girls behave, even though I have explained that that's not necessarily true."

"My daughter studies in an all-girls school and my son goes to a co-ed school. The advantage of a single-gender classroom as far as my daughter is concerned is that she does not need to mind herself all the time or be conscious about her actions as she is in an all-girls school."

Tasneem Aakbari-Kutubuddin 

Ultimately though, as parents, you will choose what you believe is best for your children. So, it is up to you to decide whether you want your children to study in a co-ed or a single-gender school. Your decision is going to shape their future, not just academically but also personally. So, choose wisely and keep an open mind.

Are There Benefits For Attending A Single Sex School? Essay

Are there benefits to attending a single-sex school? “If you want your daughter to be a high-flying businesswoman or banker, send her to a single-sex school.” (The Guardian online) New research concludes consistency in relationship between gender and education styles. Single gender classes perform better when separated in their pre-teens. It is not only the religious aspect of education ; it is a proven fact that girls and boys learn differently. They have different physical and emotional needs to learn successfully. And where does the argument about single-gender schools stop? Should we educate races, religions and members of different social classes separately? For many years, in many cultures single gender schooling is advocated on the basis of tradition as well as religion, and is practiced in many parts of the world. Recently, there has been a great deal of evidence to suggest boys and girls behave and respond differently to learning styles. Supporters believe that single gender school aids student outcomes difficulties related to hormonal and emotional maturity. Enemies, however, doubt that the evidence for such effects students and instead stating that such segregation can cost students social and relationship skills. Nowadays, girls outperform boys in almost every academic subject. It is a very well-known fact that around the world today females out number males in graduating college. It is another evidence of research conclusions on how girls and boys are

Single-Sex Classrooms Are Not The Answer! Essay

  • 8 Works Cited

An article that was written about a school in Texas stated that more than 50% of boys and girls in single-gender classrooms cause disruptions, and they bring their behavior from home into the classrooms at school. In an article, it stated that “in October of 2006, federal regulations established the requirements for legally permissible single-sex schools and classes within the public system; nearly 200 schools in South Carolina have single-gender classrooms” (“Single-Sex Education Spreads” 2). Teachers’ interest often drives the attention of students to single-gender classes, and growing interest from their parents is also pushing more schools and districts as they hear about these classrooms (“Single-Gender Classrooms” 2). While teachers and administrators prefer this environment, boys and girls in single-sex classrooms are influenced to distract and be distracted by their friends, and the people around them. They seem to doodle, daydream, and lose their thought in the classroom because of their surroundings. In a newspaper article, “Should Children Be Taught in Single-Sex Classrooms”, the author says pupils fail to develop relationships with the opposite sex if they are taught in a single-sex environment because they both tend to be drawn into conflict amongst each other, they are distracted by what others are doing in the classrooms, and they are not themselves because they are being forced into an unfamiliar environment they do not

Separate And Unequal Analysis

The programs that seperate the sexses in schools are usually based on very questionable science about the differences of girls’ and boys’ brains during development and learning, along with gender stereotypes. The American Civil Liberties Union’s article, ‘Sex-Segregated schools; Separate and Unequal’ says,” Advocates tell teachers that: Boys need a competitive and confrontational learning environment,

Disadvantages Of Single Sex Education

Single sex education, which is also known as single gender school is an old approach that’s is gaining new momentum. Single sex education consists of separating males and females into different classrooms or in separate buildings or schools. Advocates of single-sex education believe that there are persistent in how boys and girls learn and behave in educational settings such difference merit educating them separately. One version of this argument holds that brains of males and females develop differently. Proponents reference these developmental differences to argue that by separating students according to their sex, the educator is able to meet the needs according to the developmental trajectory of the different genders. In addition to that,

Does Gender Play a Role in Academic Success?

We all know the obvious difference in boys and girls. Typically, we associate boys with being rougher than girls and spending much of their time playing rambunctiously and getting dirty while most girls prefer to be subdued and tidy. But is that the only dissimilarity in gender? What about school work and academic performance along with academic success? Can gender be a predominating factor in determining a child’s IQ level? Is there a legitimate difference in boys and girls when determining academic ability? And, does gender help determine any level of academic success? Some might say that these are some pretty absurd questions but others who have taught both boys and girls in

Pros and Cons to Single-Sex Schools

Tom Carroll, the creator of Brighter Choice Charter Schools, in support of this proposition states that the key to success in education “ is to eliminate social distraction” which in elementary students he describes as “goofiness” and in older generations as “ the hormonal issues of attraction and sex and boys and girls being impressed with each other”(Meyer). Single-gender schools remove the mentioned hormonal issues and allow teachers and students to both focus on the subject without the usual distraction and complications that arise when both genders are present. In this way, students perform better when segregated by genders and achieve higher proficiency in subjects.

Persuasive Essay On Single-Sex Education

According to an article from (www.nea.org) “Male dominance in the classrooms may come as no surprise to advocates in single gender education who suggest that boys and girls are regularly treated differently in coeducational settings and that both boys and girls could both benefit from single-gender classrooms. Studies suggest that when boys are in single-gender classrooms, they are more successful in school and more likely to pursue a wide range of interests and activities”. Many would agree with this quote because they feel that males and females learn better and would be more successful separated due to no distractions in the classrooms while others might have different beliefs that both genders could be successful in the same classroom because of the contrasting opinions of others and that could be a big help in preparing them for the “real world” because they would know that everyone would have different opinions about situations that get discussed in a classroom and they would most likely know how to take criticism from both genders.

Single-Sex Schooling Causes Stereotyping and Legitimizes Institutional Sexism

  • 13 Works Cited

There is a long history of single-sex schooling, in which males and females attend specific classes or schools only with members of their same sex. This separation of genders may be done for educational purposes or in combination with other factors, such as social interactions that occur between male and female students. There is some support for the idea that single-sex schooling can be beneficial, especially for outcomes related to academic achievement and more positive academic aspirations (Lee, 2008). Although, there are many benefits of children attending single-sex schools, evidence shows that sex segregation can also gender stereotyping and legitimizes institutional sexism (Kennedy, 2000).

Single Sex School Essay

Single sex schools have less distractions in class. I believe this because in a single sex environment boys do not feel the need to impress girls and girls would not have to downplay their strengths to impress boys. The first example to backup my point is a study by the Australian Council for Educational Research where they said “research indicates that single sex schools improve

Pros And Cons Of Same Sex Schools In Public Schools

Not only does single-sex education create negative transitions into society, but it has been shown to negatively affect boys health and maturity. There has been many studies that show that girls do in fact, have a positive influence on a boy’s maturity. Theoretically it would only be the same in single-sex classrooms. Girls in school, typically have much higher concentration and ability to understand the lesson being taught to them. When in an environment with girls, the boys are able to think in a different way than in an all boy class, because the girls focus in on different perspectives that a guy’s maturity level would not usually be able to comprehend (‘pros

Single Sex Schools Are Effective Or Ineffective

Single-sex schools have proven to be effective according to many researchers. Janice Streitmatter, a researcher, shows a research where students who attended single-sex schools always score higher in their exams than students who attend coed schools. In another research she explains the outcomes on

Single Sex Schools : Primary Schools

Single-sex schools, specifically primary schools, are more beneficial to students because they facilitate higher test scores, superior academic outcomes, and greater engagement in school activities. Parents and educators have debated since the early nineteenth century whether to educate students in single-sex or co-ed schools. Currents studies have shown that single-sex schools achieve higher in academic success. Students with higher academic success become adults with a brighter future that can benefit society.

The Pros And Cons Of Single Sex Education

Single sex schools would also increase the academic potential of students by eliminating the male dominated classroom and replacing it with a level playing field for males and females. Stated in the article “research

Pros And Cons Of Single-Gender Education

There are strong claims for and against single-gender education around the globe. Despite extensive research in developing effective teaching practices for boys and girls separately, there are fundamental similarities between meeting the educational needs of girls and boys. There are more commonalities between the two than there are dissimilarities. Boys and girls seem to elicit different kinds of teaching they need due to the constraints that social norms put on each gender. For countries with European roots in their culture, this is also true. Although certain sex-linked characteristics are biologically inherent, how one learns is not dependent on their gender. Both girls and boys are relational learners, educe the kinds of teaching they need and find greater meaning in lessons they find interesting. It is not what sex individuals are born as that dictates what kinds of teaching methods they require, but rather it is how they are designed by their environments that shape their needs. This is particularly true for girls; and even more so for girls of color.

Pros And Cons Of Single Sex Schools

Single sex schools are common within the fait schools and some schools who believe there association within their faith would work out better within a diverse atmosphere. Some believe that having single sex schools is a good idea because then boys would feel more concentrated with their school work instead of trying to impress or compete for the girls. Parents also believe that boys would participate more and be focus with their education if girls were not in the same class as them. As a result, single sex schools should be banned to give children the opportunity to gain a better education and interacting with the opposite sex. Teaching boys and girls in separate classrooms it’s an old approach in which has recently gained momentum. The reason being is some debate on the fact that it reduces boys’ and girls’ opportunities to work together, and reinforces sex stereotypes while others believe that single-sex schooling results in better academic outcomes. Although there has been multiple case studies to find some common ground or to see which one is more beneficial or affective the results fluctuates.

Single Sex And Co Educated Schools

Do people really expect for a child’s grades to improve at an instant? Psychological problems will begin to increase if students do not interact with the opposite sex. Students will lack the advantages of the co-educational elementary, middle, and high school experience. Society may claim a single sex school environment will completely help develop education for students, but they are wrong.

Education is a conventional mode of receiving knowledge needed for people to pursue professional aspirations. What shape such aspirations are schools that narrow children’s scope of interests, determine the areas of expertise and, most importantly, provide with knowledge. To make school environment better in terms of efficiency, school officials came to introduce class differentiation years ago. The system of single-class schools had not regained its popularity with American parents until 2000s. On paper, single class schools handle the problem of bullying, however, not necessarily. Better school performance and mental skills development are believed to be the case in such schools in spite of possible criticism. Overall, school students achieve better results though the instrumentality of gender separation; however, there are a variety of disadvantages not be counted away. Novotney (58) notes that since “No Child Left Behind” Act being signed into law back in 2002, the popularity of single-sex education has been on the rise. This piece of legislation made it possible for regional educational agencies to apply the funds of the so-called “Innovative Programs” for lending support to same-gender classrooms and schools in line with the existing legislation. The US Department of education, in turn, reduced restrictions on single-sex education by easing its Title 9 regulation in 2006. As of today, there are a total of 95 single-sex public schools, as per NASSPE, or the National Association for Single Sex Public Education, with as many as 445 public coeducational schools offering single-sex classrooms. According to Leonard Sax, philosophy doctor and NASSPE executive director, it is not that separating boys and girls grants success; it is that such schools take advantage of gender-specific teaching methods instrumental in identifying boys’ and girl’s merits and strengths. Such mode of education is popular, not but that a good number of experts are inclined to believe that single-sex class success originates in both the focus on extracurricular activities and a demanding curriculum irrespective of whether or not the opposite sex was present (Novotney 58). Anyway, parents ought to think long and hard before making the decision of sending their children to single-sex schools, as there are clear arguments and counterarguments of doing so. The proponents of single-sex education insist on brain difference being one of key rationales for class separation. A longitudinal pediatric neuroimaging study from 2007 conducted by neuroscientist team from the National Institute of Mental Health have concluded that different brain areas tend to develop in a different tempo and sequence in girls as compared to boys. The occipital lobe linked to visual processing shows the signs of development in girls aged between 6 and 10 years, whereas boys have the region cells grow until after they turn 14 years of age (Novotney 58). With that in mid, the expert points to the brain properties of girls developing at a much faster pace as opposed to boys, which rationalizes class separation, as girls require exercises developing these areas of brain much earlier than boys do. Hence, class segregation creates opportunities for a more harmonious development of school students based on the principle of organism maturation, so to speak. Novotney (58) goes on to note that studies on gender language divergence have demonstrated that three-year-old girls’ language processing far outpaces that of five-year-old boys. It is safe to assume that, in dividing classes on the basis of gender, educators are afforded the ample opportunity of employing language-based exercises, with the members of the same sex in class. Thus, the value of such exercises will be proportionally distributed among all the students, bar none, more importantly, students whose brain has matured enough to apprehend information. Parker and Rennie (n.p.) admit that teachers may employ not only instructional techniques, but also exercises that boys believe more exciting, which will activate their attention and information apprehension (qtd. in Briegel 6). NASSPE (n.p.), Parker and Rennie (n.p.), Warrington and Younger (n.p.) are convinced that class separation allows educators to use whatever technique necessary, without having to alternate one method with the other (qtd. in Briegel 6). According to Novotney (58), psychologist and philosophy doctor, Lisa Darmour claims same sex classes to enable teachers to apply strategies inapplicable in coeducational classes. To quote an example, boys are good at math courses while girls show shows shades of doubt, when dealing with difficult math-related material, as per Carol Dweck, philosophy doctor and Stanford University psychologist. It is worth noting that Lee and Bryk (387-388) observations are indicative of single-sex schools girls’ and boys’ performing more homework for their classes, as compared with their unisex school counterparts. In addition, boys from single-sex classes were more willing to join science and mathematics courses than their peers from schools for both sexes were (qtd. in Briegel 7). Unlike their coeducational-class peers, girls from single-sex classes, according to Gillibrand, Robinson, Brawn, and Osborn (356), show abiding faith in their physics knowledge, which leads them to join respective courses and score high test results. Girls, in their turn, appear hesitant and less willing to become actively involved in laboratories in unisex classes, with boys more superior to them in physics (qtd. in Briegel 7). Riordan (n.p.) notes that, of both sexes, girls appear to benefit more from a single-sex education mode. Boys and girls, whether from Catholic or public high schools, far outclassed their peers from unisex schools in math scores (Streitmatter 37). To overcome complexes, to deal with gender and inferiority stereotypes, and to strengthen students’ educational determination is what single-sex system is all about. Parker and Rennie (n.p.) claim single-sex classes to enhance internal cooperation and make student-to-student interaction more respectful in all-girl classes. Lisa Darmour believes that one-sex schools help students concentrate more on studies rather than opposite sex peers, they feel affection towards and try to put it on display (Novotney 58). Lee and Bryk (n.p.) also agree on the point that opposite gender no longer poses distraction in single-sex classrooms, with student contingent composed of peers supportive of other children’s comments and ideas. Interestingly, once in such educational environments, girls fall to pursuing the so-called male-dominated disciplines, such as the sciences, mathematics, and the industrial arts (qtd. in Briegel 5). According to Warrington and Younger (n.p.), when in single-sex environment, boys may go all the way to taking academic risks since getting ashamed is far easier to take in the group of males than if it were in a unisex classroom (qtd. in Briegel 6). Zero girls’ presence may incite boys to assume role they perceive as being masculine. Whatever advantages, class segregation has plenty of negative implications and consequences in it. According to Novotney (58), coed proponents and researchers report classroom segregation to result in a greater gender discrimination, whether it be at school or in classroom. Students were also reported to have problems dealing with the opposite sex in their later life. Schools are the preparation for adult life, as per Diane Halpern, APA ex-president, that is to say, it is exactly at school that boys and girls learn how to cooperate with each other. While in the workplace, they are sure to have issues of interaction with opposite sex colleagues, without having this type of experience at school. Halpern, Eliot, Bigler, Fabes, Hanish, Hyde, Liben, and Martin (1707) suggest that, apart from decreasing boys’ and girls’ opportunities of working together, separation causes them to spend the minimum amount of time with opposite sex peers. Boys’ spending more time with other boys grow aggressive and develop behavioral problems with time, which does not allow them to assume a wider range of attitudes and behaviors (Halpern, et a. 1707). A study conducted by Doctor Lynn Liben and her graduate student, Lacey Hilliard showed that class segregation contributed to stereotypical attitude increase, which was in inverse proportion to the interest of playing with opposite sex peers (Novotney 58). Children come developing gender stereotypes in environment where gender division is explicit, which has the potential of causing interpersonal relationship issues at some point in the future. Education equity director with the Feminist Majority Foundation, Sue Klein suggests that class division produces inequality; what is more, plenty of single-sex classrooms and schools overstate and induce sex stereotypes by putting focus on aggression and rivalry among boys and inactivity among girls by means of setting expectations about boys’ not being good at writing. According to Halpern, Eliot, Bigler, Fabes, Hanish, Hyde, Liben, and Martin (1707), some scientists insist as if class segregation eliminated sexism, or gender stereotypes suggesting men’s superiority over women. Children start regarding sex as a core human attribute as well as developing strong intergroup biases. Novotney (58) admits that the biggest problem is that a good many educational problems sex-separated public educational programs are illicit inasmuch as they do not provide parents with a coed choice for children. More importantly than that, schools officials do not display the interconnection between single-sex program and educational goal (Novotney 58). According to Bailey (n.p.), single-sex schools blight the decades of anti-segregation civil movements and sex-related discrimination cessation attempts. In Arlington Community High School and a number of other educational establishments, educators have come to separate students in lunchrooms, hallways, and even school buses while other schools have established separate classes for both sexes in physics and algebra. Not only does deepen the once battled sex-based societal segregation, but it also creates judicial collision. To put an example, it was because of segregation that West Virginia middle school program controversy required hearing and settlement in court. The program imposed different expectations of girls as well as boys, with the latter permitted plenty of moving about and the former ordered to sit quietly. Overall, far from yielding no results due to, segregation is the sources of many long-term problems (Bailey n.p.). Clearly, it is no good telling some students, for example, that they are excellent at subjects other than exact sciences by virtue of gender stipulated laws. Such an imposed attitude will most likely live a mark on the vision of their future profession. Studies conducted by neuroscientists, and legal scholars have proved that segregation based on sex boosts discrimination and helps children develop sex stereotypes that are prerequisite to them engaging in drug abuse, unprotected sex, and aggression. Newly converted schools often force students unwilling to attend unisex classes into transferring to lower-quality schools. Worse, single-sex schools are an expensive educational option. With that in mind, there should be more affordable coed alternatives to such schools without the shortage of experienced educators, better athletic opportunities, and more afterschool options, and what distinguish single-sex schools from unisex establishments are these three options (Bailey n.p.). Conley (n.p.) also puts focus on the possibility of children’s developing gender stereotypes, which is among one of the most negative outcomes of unisex learning mode. Halpern, Eliot, Bigler, Fabes, Hanish, Hyde, Liben, and Martin (1706) claim that gender distinction is of huge academic value to students; however, such statement may have no scientifically proved grounds. Students already have a higher academic level on entering single-sex schools and had better test scores one year prior to being admitted. In other words, academic successes are mostly anyone else’s merit but that of SS schools. This is not all there is to it since underachieving students tend to transfer out prematurely, which inflates performance results. Exist as successful single-sex schools might, there is no evidence that their organization, a demanding curriculum, and other aspects boost students’ academic performance. If truth be told, the supposedly axiomatic concept of brain difference central to single-sex educational principle does not seem to stand to criticism since neuroscientists have hardly found any differences save for boys’ brain larger volume and girls’ brain cells earlier growth completion, of which neither bears relation to learning and academic success. Nor is the argument of both sexes having different autonomic nervous system function scientifically correct (Halpern, et al. 1707). Strain (29) states that, despite a well-developed stereotype of performance academic improvement, SS math classes damage students’ end-of-grade scores of mathematics and reading tests. Finally, according to Taylor (n.p.), studies have demonstrated that children from single-sex schools are no different than their counterparts who stem from unisex schools, which refutes the popular belief, based on which unisex schools and classes provide children with knowledge needed for them to master STEM or science, technology, engineering, and math subjects. Conley (n.p.) also insists that there are distinctions between single-sex schools students and their peers from conventional unisex schools in terms of knowledge an academic success. Such children are far more likely to join subject courses than their peers from unisex schools are. However, single-sex schools are also said to produce stereotypes and be the source of sexism. Children from such classes will likely have problems socializing with opposite sex counterparts while in the workplace. Plenty of scientists claim students from separated classes to show the exact same academic performance as their peers from unisex classes do. Attitudinal, behavioral problems, substance abuse, unprotected sex, and aggression are possible fallouts of single-sex education. That being said, it is highly doubtful that such approach to plying school students with knowledge should be applied very carefully, if at all since there are plenty of weighty arguments against it.
